This is what the Indian Met Department says of the depression (deep depression) that has formed in the Bay of Bengal.
Dated: 17.06.2011
Sub: Deep depression over Gangetic West Bengal and adjoining Bangladesh.
The deep depression over Gangetic West Bengal and adjoining Bangladesh remained practically stationary and lay centred over Gangetic West Bengal and adjoining Bangladesh at 0530 hrs IST of today, the 17 June 2011, near lat. 22.50 N and long. 89.00 E, about 130 km northeast of Sagar Island, 80 km east of Kolkata and 150 km west-northwest of Khepupara (Bangladesh). The system is likely to move north-northwestwards initially and then west-northwestwards and weaken gradually into a depression during next 24 hours.
Under its influence, rain/thundershowers at most places with heavy to very heavy falls at a few places would occur over north Orissa, Jharkhand and coastal districts of West Bengal during next 48 hours. Isolated extremely heavy falls (25 cm) would also occur over north Orissa during the same period. Rainfall at most places with isolated heavy to very heavy falls would occur over south Orissa, Chhattisgarh and remaining parts of Gangetic West Bengal during next 48 hours.
Squally winds with speed reaching 45-55 kmph gusting to 65 kmph would occur along and off north Orissa and West Bengal coasts during next 12 hours. Sea condition will be rough to very rough along and off these coasts. Fishermen are advised not to venture into the Sea off these coasts during next 12 hours.
The system is under constant watch and concerned state Govts are being informed accordingly.
This is the first depression/low pressure area that has formed in the Bay of Bengal. One may note that the early low pressure areas in the Bay of Bengal move westward (Towards western states of India). But as the monsoons progress, they start shifting to a north-westerly and a northerly direction (moving towards Uttar Pradesh and Bihar).
This particular storm is going to bring a lot of rainfall to many states in India, starting with Bengal,Orissa, Bihar, Jharkhand, Chattisgadh, Madhya Pradesh, parts of Maharashtra and then some precipitation in Gujarat! A busy guy! But the rain system will reach Gujarat (a very weak system by that time) after a week. It will traverse India east to west in one week.
