Fresh monsoon surge over South, West Coast as Bay bristles with action
A red-hot Bay of Bengal hosting angry thunderstorms over waters as well as over adjoining East Coast has catapulted the monsoon to a new high even as a fresh low-pressure area is expected to form over these waters in next two days.

An expected fresh monsoon surge is materialising over the South Peninsula and West Coast into the last week of July while parts of East and Central India and North-West India continued to receive heavy to very heavy rainfall from benign conditions anchored by weather systems over land and the Bay of Bengal. Strong surface winds with speeds reaching 40-50 km/hr have been forecast over the South Peninsula during next five days, which will help hold up a strong monsoon for as many days.
Rain systems on high
The systems converging to drive monsoon to a high include the monsoon trough that passes through Firozepur, Karnal, Meerut, Varanasi, Jamshedpur and Digha before dipping into east-central Bay of Bengal. An upper air cyclonic circulation hung over south-west Rajasthan while a western disturbance persisted over Jammu & Kashmir and adjoining Himachal Pradesh.
Buzzing Bay waters
The buzzing Bay waters are ratcheting up proceedings by hosting a circulation over west-central and adjoining north-west Bay while an incoming circulation from South China Sea cyclone Wipha may emerge over the north Bay by Thursday. Both these will merge to set up a fresh low-pressure area by Friday. A helpful trough runs from north-east Arabian Sea to the west and adjoining north-west Bay across South Gujarat, north Madhya Maharashtra, Vidarbha, Telangana and Coastal Andhra Pradesh.
Extreme heavy rain
Given this setting, the India Meteorological Department (IMD) has predicted extremely heavy falls for a rain-battered Coastal Karnataka for three days from Wednesday; over Konkan and ghat areas of Madhya Maharashtra on Thursday and Friday; and over Odisha on Friday as a series of cyclonic circulations and troughs continued to hold sway over monsoon from early this week.
The 24 hours ending on Wednesday morning saw extremely heavy rain being reported from Telangana; heavy to very heavy rain from East Rajasthan; West Madhya Pradesh; Konkan and Goa; rest of Telangana; and Coastal Karnataka. It was heavy in other arts of Konkan and Goa and Odisha; deficit-ridden Bihar; Uttarakhand; Punjab; east Gujarat; Madhya Maharashtra and Chhattisgarh;
Kerala, Coastal Karnataka
The next seven days may bring heavy to very heavy rain over Kerala, Mahe, coastal and south interior Karnataka, coastal Andhra Pradesh and Yanam in a sustained southerly monsoon push. It will be isolated heavy over Tamil Nadu and Telangana for five days from Wednesday; isolated very heavy rainfall over Telangana on Wednesday and Thursday.
Rain for West Coast
Heavy to very heavy rainfall is likely over Konkan and Goa and ghat areas of Madhya Maharashtra for seven days while it will be heavy over a deficit-ridden Marathawada only for a day on Saturday while being extended for seven days over east Gujarat for seven days and Saurashtra and Kutch for four days, with isolated very heavy rainfall over east Gujarat on Sunday and Monday.
East, Central India
Isolated heavy rainfall may continue over Madhya Pradesh, Vidarbha, Chhattisgarh and Odisha for six days; over West Bengal for four days; Bihar and Jharkhand from Thursday; and hills of West Bengal and Sikkim for three days. It will be isolated very heavy over West Madhya Pradesh for three days from Saturday; East Madhya Pradesh for four days from Friday; Vidarbha and Jharkhand for three days from Friday; Chhattisgarh and Odisha for three days from Thursday; and over West Bengal on Thursday and Friday.
