The Bay of Bengal is being put under watch for cyclone formation as an existing depression in the Gulf of Thailand sails into South Andaman Sea where enabling conditions are building up.
A Thai Met Department update on Monday said that the tropical depression in the lower Gulf of Thailand was centred about 160 km east of the nearest Southern Thailand coast with sustained winds speeding up to 50 km/hr.
THAILAND LANDFALL
The system has been moving in a northwest direction at a speed of 15 km/hr and is expected to make landfall over the southern provinces during the night itself.
Both sides of the Thai Gulf would remain cloudy with fairly widespread thundershowers and heavy to very heavy rain. Northeasterly winds are expected to clock 28 to 50 km/hr.
As for the Andaman Sea, the Thai Met Department has forecast cloudy weather with fairly widespread thundershowers and isolated heavy rain in the lower Andaman Sea and Malacca Strait with wind speeds touching 50 km/hr.
IMD JOINS WATCH
India Meteorological Department (IMD) joined a number of international weather models in mounting the watch for the possible cyclone, materialising close on the heels of Super Cyclone Giri that hit the Myanmar coast last week.
The brewing cyclone could be racing towards the Tamil Nadu-South Coastal Andhra Pradesh coast for a landfall, say consensus predictions.
But the US Navy model saw the storm progressing west from the South Andaman Sea in a linear fashion and hitting Sri Lanka.
LANDFALL OVER TN
The landfall could take place by the weekend and the weakened storm is expected to head north-northwest into Western Maharashtra before being guided north-northeast by possible westerly winds into West Madhya Pradesh.
Two dedicated cyclone tracking models, Roundy-Albany and the Central Weather Bureau of Taiwan, too seemed to signal the North Tamil Nadu (including Chennai)-South Coastal Andhra Pradesh for a landfall for the building storm.
WIDESPREAD RAIN
A weather warning issued by the IMD said that isolated heavy to very heavy rainfall would occur over coastal Andhra Pradesh, Andaman and Nicobar Islands and south Karnataka during the next two days.
It would be isolated heavy rainfall over Tamil Nadu, Rayalaseema and Kerala on Tuesday.
During the 24 hours ending Monday morning, widespread rainfall has occurred over coastal Orissa and coastal Andhra Pradesh, an IMD update said.
It was fairly widespread over interior Andhra Pradesh, Tamil Nadu, coastal and south interior Karnataka and Kerala and scattered over Chhattisgarh and interior Orissa.
CLOUD IMAGERY
Satellite cloud imagery showed the presence of convective clouds over parts of West-central and south Bay of Bengal, south Andaman Sea, southeast Arabian Sea, South Orissa, south Chhattisgarh, coastal Andhra Pradesh, south Karnataka and Tamil Nadu.
The causative upper air cyclonic circulation over West-central Bay of Bengal and adjoining South Coastal Andhra Pradesh persisted.
Forecast until Thursday spoke about the possibility of widespread rain or thundershowers over coastal Andhra Pradesh.
It will be fairly widespread over Tamil Nadu, the rest of Andhra Pradesh, South Karnataka, Kerala, Lakshadweep and Andaman and Nicobar Islands.
Scattered rain or thundershowers would occur over north Karnataka on Tuesday and may increase thereafter.
Fairly widespread rain or thundershowers are likely over Gangetic West Bengal, Jharkhand, Orissa and Chhattisgarh on Tuesday.
