12 Oct – The IMD has issued its evening alert on cyclone Hudhud. The 1700 IST (5:00pm IST) alert contains a heavy rainfall warning and a wind warning.

Heavy rainfall warning: Rainfall at most places with heavy (6.5-12.4 cm) to very heavy falls (12.5-24.4 cm) at a few places and isolated extremely heavy falls (>24.5 cm) would occur over West and East Godavari, Visakhapatnam, Vijayanagaram and Srikakulam districts of north Andhra Pradesh and Ganjam, Gajapati, Koraput, Rayagada, Nabarangpur, Malkangiri, Kalahandi, Phulbani districts of south Odisha during next 24 hrs. Rainfall would occur at most places with heavy to very heavy rainfall at isolated places over Krishna, Guntur and Prakasham districts of Andhra Pradesh and north Odisha during the same period. Rainfall at most places with heavy falls at a few places would occur over south Chattisgarh, adjoining Telangana and isolated heavy to very heavy falls over north Chattisgarh, east Madhya Pradesh, Jharkhand and Bihar.

Cyclone Hudhud will degrade into a severe cyclonic storm, then a cyclonic storm and by 13 October morning into a deep depression. Until 14 October it will continue to pose a danger with heavy rainfall and high winds. This IMD table explains why.

There are reports on twitter that the leading edge of cyclone Hudhud crossed the coast at around 1030 IST (0500 UTC). The reported maximum wind speed is just above 200 kmph which means the destructive force threatens structures too.

This tweet means that western ‘wall’ of the cyclone has crossed. It took just under two hours. The eastern ‘wall’ crossing of the coast, accompanied by severely high winds and very heavy rain, is under way now.

Navy officials warn that there will be a lull in the storm at around 11.30 am, but the storm will again intensify after that for a few hours.
Zee News has a list of cancelled and curtailed trains.
At least 400,000 people have been evacuated from the coastal areas of Andhra Pradesh and Odisha states as authorities aimed for zero casualties.

11 Oct – Where is Cyclone Hudhud and how fast is it moving towards land? The India Meteorological Department has said in its most recent alert – 1430/2:30pm on 11 October – that “the Very Severe Cyclonic Storm” is now about 260 kilometres south-east of Visakhapatnam and 350 km south-south-east of Gopalpur. IMD expects the cyclone to travel north-west and cross the coast of north Andhra Pradesh, near Visakhapatnam, by mid-morning on 12 October 2014.

Around 100,000 people have been evacuated in Andhra Pradesh to high-rise buildings, shelters and relief centres, with plans to move a total of 300,000 to safety. Authorities in Odisha said they were monitoring the situation and would, if necessary, move 300,000 people most at risk.

The evacuation effort was comparable in scale to the one that preceded Cyclone Phailin exactly a year ago, and which was credited with minimising the fatalities to 53. When a huge storm hit the same area 15 years ago, 10,000 people died.

Authorities have been stocking cyclone shelters with dry rations, water purification tablets and generators. They have opened up 24-hour emergency control rooms and dispatched satellite phones to officials in charge of vulnerable districts.

The AP government has cancelled leaves of employees and has asked everyone to remain on duty on the weekend.  In Vizag, where the cyclone is expected to make landfall, the administration has opened 175 shelters and moved close to 40,000 people from the coastal villages. In Srikakulam, people of 250 villages in 11 mandals which may be affected have been evacuated.

While human casualties are not expected due to the massive evacuation, power and telecommunication lines will be uprooted leading to widespread disruption. A warning has been issued that flooding and uprooted trees will cut off escape routes, national and state highways and traffic is being regulated to ensure that no one is caught in the flash floods caused by heavy rains.

Officials said that National Disaster Response Force teams have been strategically placed along the coast to be deployed wherever they are required. Railways has cancelled all trains passing through the three districts which are likely to be affected.

The IMD has issued a “Heavy Rainfall Warning” which has said that driven by the cyclonic winds, rainfall at most places along the AP and Odisha coast will be heavy (6.5–12.4cm) to very heavy (12.5–24.4 cm). These places include West and East Godavari, Visakhapatnam, Vijayanagaram and Srikakulam districts of north Andhra Pradesh and Ganjam, Gajapati, Koraput, Rayagada, Nabarangpur, Malkangiri, Kalahandi, Phulbani districts of south Odisha.

10 OctThe India Meteorological Department said on the evening of 10 October that the “Very Severe Cyclonic Storm” is centered near latitude 15.0ºN and longitude 86.8ºE about 470 km east-southeast of Visakhapatnam and 520 km south-southeast of Gopalpur. This was the fix IMD had on the centre of the cyclone at 1430 IST on 10 October 2014.

Here are the salient points from news reports released during the afternoon of 10 October:

Cyclone Hudhud will cross the north Andhra Pradesh coast on October 12 and is expected to make landfall close to Visakhapatnam, according to the Cyclone Warning Centre (CWC) at Visakhapatnam. “It is forecast that Hudhud, which is already a severe cyclonic storm, will intensify into a very severe cyclonic storm in next 12 hours. Hudhud is likely to make landfall on October 12 close to Visakhapatnam,” said IMD’s Hyderabad centre.

Cyclone Hudhud has moved closer to the coast of Odisha and eight districts of the state are likely to be affected by it. The districts likely to be affected by the cyclone are Ganjam, Gajapati, Rayagada, Koraput, Malkangiri, Nabarangpur, Kalahandi and Kandhamal. All these districts have been provided with satellite phones for emergency and constant vigil was being maintained on the rivers like Bansadhara, Rusikulya and Nagabali as heavy rain is expected in southern districts.

The path over the Bay and after landfall as forecast by the IMD's Regional Specialised Meteorological Centre (RSMC). Note that within the large circle of heavy rainfall expected inland are the cities of Nagpur, Nanded, Amravati, Bhilai, Raipur and Karimnagar.

With cyclone Hudhud fast approaching the states of Odisha, Andhra Pradesh and Telangana, Union Home Minister Rajnath Singh today spoke to the chief ministers of the three states on the steps being taken to deal with the situation. Odisha Chief Minister Naveen Patnaik sought satellite phones which could be used in case high-speed winds disturbed the telecommunication system.

According to the India Meteorological Department, the wind speeds of cyclone Hudhud will be less than what the east coast experienced during Phailin in October 2013. The wind speed during cyclone Phailin was nearly 210 kmph, which made the cyclone the second-strongest ever to hit India’s coastal region. The country had witnessed its severest cyclone in Odisha in 1999.

Frequent updates and advisories can also be found at GDACS – the Global Disaster Alert and Coordination System (a cooperation framework under the UN umbrella). GDACS provides real-time access to web-based disaster information systems and related coordination tools.

Cities that will directly be affected by cyclone Hudhud are Vishakhapatnam in Andhra Pradesh, Jagdalpur in Chhattisgarh, Vizianagaram in AP, Bhogapuram in AP, and Anakapalle in AP.

Preparing for Cyclone Phailin

leave a comment »

RG-Phailin-eastern_India_rain_peak_201310Update4: The water carried over land by Cyclone Phaillin has now travelled northwards and west. Daily monsoon system monitoring by the Centre for Ocean-Land-Atmosphere Studies – COLA (a scientific research centre to improve understanding and prediction of Earth’s climate variations) now show the danger from very heavy rain to districts in interior Odisha, eastern Madhya Pradesh, Chhattisgarh, Jharkhand, Bihar and eastern Uttar Pradesh.

The soil moisture in these regions is already high – as it should be at the end of the south-west monsoon – and very heavy spells of rain approaching 20mm in three hours will cause widespread flooding. The National Disaster Management Authority and the armed forces will continue to have to be on the alert for flood-related rescue calls from these regions.

Update3: It is very worrying to find that:

(a) satellite images shared by a global meteorological community are showing that Cyclone Phailin crossed the Indian coast between 1800 and 1900 (6pm and 7pm) but until well after 1900 (7pm) the Indian Meteorological Department told television news channels it was still approaching, and

The NOAA image dated 12 October 2013 and timed at 1400 UTC which shows the eye of Phailin having crossed the Indian coast in Srikakulam district, Andhra Pradesh.

The NOAA image dated 12 October 2013 and timed at 1400 UTC which shows the eye of Phailin having crossed the Indian coast in Srikakulam district, Andhra Pradesh.

(b) that hourly data from the automated weather stations on the eastern coast are not visible – no explanation as to whether they had been knocked out by the cyclonic conditions or whether the data links were down.

Update2: The armed forces and para-military and disaster relief and rescue teams are reported to be ready. Two Indian Air Force IL-76 aircraft have taken teams and equipment to Bhubaneshwar, Odisha. The Indian Air Force is on stand-by at various bases including Raipur, Nagpur, Jagdalpur, Barrackpore, Ranchi and Gwalior. At least 28 teams of the National Disaster Response Forces have been mobilised.

Important advice from the National Disaster Management Authority of India – If you are in the cyclone danger zone: check the house; secure loose tiles. remove dead wood or dry branches close to the house. Anchor movable objects like piles of wood, tin sheets (these are deadly when sent flying during a cyclone), loose bricks, rubbish bins (whose lids can fly like dangerous missiles in high wind), unbolted sign-boards.

Keep a few wooden boards, nails and a hammer ready to board up glass windows if they are in danger of shattering inwards. Keep emergency lighting ready. Ensure mobile phones are charged. Keep battery-operated torches ready batteries handy. Store boiled or filtered water for drinking. Keep dry food (such as biscuits) at hand if conditions worsen and you can’t cook a hot meal.

Zee News (television and online) has reported that in Odisha “thousands flee to shelter homes stocked with emergency food supplies and medicines”. National Disaster Response Force (NDRF) teams have reached Bhubaneswar (capital of Odisha) as evacuations have begun in Odisha and north Andhra Pradesh. Union Defence Minister A K Antony has asked armed forces to be ready to move in to Odisha and Andhra Pradesh.

NDTV (television and online) has reported that five districts “are preparing for the worst impact of the cyclone: Srikakulam in Andhra Pradesh and Ganjam, Puri, Khordha and Jagatsinghapur in Odisha.” Helicopters and food packages are ready for areas that are likely to be worst hit. A minister in the Andhra Pradesh state government has reportedly said that 64,000 people are being evacuated from Srikakulam, Vishakhapatnam and Vizianagaram and are being shifted to cyclone shelters.

The forecast six-day path of cyclone Phailin.

The state of Odisha is preparing for Cyclone Phailin as it approaches from the Bay of Bengal. Consult the new map of Phailin and its possible pathways from the Global Disaster Alert and Coordination System (GDACS).

My reading of the forecast path of the cyclone – using the map sets from the National Centre for Medium Range Weather Forecasting (Earth System Science Organisation, Ministry of Earth Sciences) – is that in Odisha the districts of Ganjam, Puri, Jagatsinghpur, Kendrapara, Bhadrak, Baleshwar, Kordha, Jajapur, Cuttack, Nayagarh and Gajapati will be in the cyclone’s path beginning with increasingly heavy rain and fierce winds from Saturday morning 12 October 2013; in Andhra Pradesh the districts of Srikakulam, Vizianagaram and Visakhapatnam and in West Bengal the districts of Purba Medinipur will be in the cyclone’s path.

RG-Cyclone_Phailin_day3_sectionThe series of stacked rainfall forecast maps above show the approach of Cyclone Phailin from 11 October.

Look for the deep blue circle in the left panel from the first pair (top left, 24 hours) – extending out ahead of the cyclone core is the rain storm, which will cross the northern coast of Andhra Pradesh. In the second pair (top middle, 48 hours), the blue circle has moved closer to the coast – rainfall from the vast gyre of clouds around the approaching cyclone will extend far inland, in a great spike through Andhra Pradesh, parts of Madhya Pradesh and north into western Uttar Pradesh.

In the third pair (top right, 72 hours), the cyclone has made landfall with Odisha in the centre and affected districts in Andhra Pradesh to the south and West Bengal to the north – this is when the disaster management teams in the districts will be taxed to the utmost, having already been battered by heavy rain and unrelenting high-speed winds for two days.

RG-cyclone_districts_20131011In the fourth pair (lower left, 96 hours) the cyclone is still very active as it moves north-west to sweep across Odisha. In the fifth pair (lower middle, 120 hours) the cyclone core has finally weakened (no longer coloured deep blue) but has moved into Jharkhand, Bihar, West Bengal and eastern Uttar Pradesh. In the sixth pair (lower right, 144 hours) the cyclone’s force has dissipated leaving rain in its wake across eastern India.

Orissa Dairy has reported (‘Phailin upgraded to super cyclone’): “The very severe cyclonic storm Phailin, expected to make landfall at Gopalpur in Odisha, moved closer to the state and lay about 600 km southeast of Paradip, as the government sought the help of defence forces to boost its preparedness, official sources said on Thursday night.”

RG-Cyclone_Phailin_day4_sectionThe Hindustan Times has reported (‘Cyclone Phailin: deep depression over Bay of Bengal intensifies further’): “A morning bulletin of Bhubaneswar meteorological department on Friday said the cyclone would move north-westward and cross Andhra Pradesh and Odisha coast between Kalingapatam (Andhra Pradesh) and Paradip, close to Gopalpur, by Saturday evening as a very severe cyclonic storm with a maximum sustained speed of 205-215km per hour.”

DNA has reported (‘Odisha braces for Cyclone Phailin’): “The state government said it was making adequate preparation to deal with the disaster that expects to cause large scale devastation mostly in state’s coastal southern districts. Durga puja festivities in Odisha have been cancelled as the state prepares for Cyclone Phailin which could be the worst since 1999 when 10,000 people died. The Air Force, Navy and national disaster management team have already been put on stand-by, while the rapid action force has deployed its forces on the ground. People in the low lying areas of the state will be evacuated by Saturday evening.”

How warm-hot-wet was 2012 September where you live?

Land-ocean temperature anomalies in 2012 September. Map: NOAA-NCDC

Wondering what global warming has to do with violent rainstorms, hurricanes, typhoons, cyclones and other enormous destructive and very wet (and cold) weather phenomena you may have experienced in 2012 September? Here is an answer, provided by the ever-watchful (and woefully under-appreciated) National Climatic Data Center of the USA’s National Oceanic and Atmospheric Administration (NOAA).

In its ‘State of the Climate’, global analysis for 2012 September, the NOAA-NCDC has said:

(1) The average combined global land and ocean surface temperature for September 2012 tied with 2005 as the warmest September on record, at 0.67°C (1.21°F) above the 20th century average of 15.0°C (59.0°F). Records began in 1880.
(2) The globally-averaged land surface temperature for September 2012 was the third warmest September on record, at 1.02°C (1.84°F) above average. The globally-averaged ocean surface temperature tied with 1997 as the second warmest September on record, at 0.54°C (0.97°F) above average.
(3) The average combined global land and ocean surface temperature for January–September 2012 was the eighth warmest such period on record, at 0.57°C (1.03°F) above the 20th century average.

This was the third warmest September over land in the Northern Hemisphere and fourth warmest in the Southern Hemisphere. In the higher northern latitudes, parts of east central Russia observed record warmth, as did parts of Venezuela, French Guiana, and northern Brazil closer to the tropics. Nearly all of South America was much warmer than average as were western Australia and central to eastern Europe. Far eastern Russia, a few regions in southern Africa, and parts of China were cooler than average.

Moreover, this was the second warmest summer (June–August) for Hungary since national records began in 1900; Australia experienced its third warmest September since records began in 1950, with the nationally-averaged maximum temperature 1.94°C (3.49°F) above the 1961–1990 average; in Argentina the monthly-averaged daily, maximum, and minimum temperatures were all above normal (and remember both Australia and Argentina are both wheat producers and exporters); Japan observed record warmth during September, the greatest warmth was observed across northern Japan (regions of Hokkaido and Tohuko), which was 3.7°C (6.7°F) above average; in Britain, the average September temperature was 0.7°C (1.3°F) below the 1981–2010 average and was the coolest September for the region since 1994 (that’s certainly linked to the Arctic sea ice melting at a record rate this year).
