Guwahati, June 11: According to the latest IMD outlook, the northern limit of monsoon has passed over southern Gujarat, southern Madhya Pradesh Chhattisgarh, and Northeast plains about five days earlier. Further, it is expected to advance into the remaining parts of Gujarat, the rest of Madhya Pradesh, Chhattisgarh, Odisha, West Bengal, and Bihar during the next few days.
Ahead of the monsoon onset, fairly widespread thunderstorm activity accompanied by frequent cloud to ground lightning is likely over Madhya Pradesh, Uttar Pradesh, Uttarakhand, Chhattisgarh, Odisha, Bengal, Jharkhand, and Bihar during the next 24 hours.
Meanwhile, a cyclonic circulation is at the northwest of the Bay of Bengal and is expected to become a low-pressure area in the next 24 hours. The system is likely to move west-northwestward heading to Odisha.
Under its influence, widespread rain and thunderstorms are expected over East and Northeast India for the next couple of days. In particular, very heavy to extremely heavy rain is forecast in isolated places of Odisha and adjoining Andhra Pradesh and Chhattisgarh through Monday with a risk of flooding, swollen rivers, and inundation in low land areas.
Furthermore, it has been forecast that the low pressure will move northwestward heading east Uttar Pradesh and be insignificant around Tuesday.
Moreover, there are possibilities of the strengthening of westerly winds along the west coast in association with the low-pressure area. Owing to this, widespread rainfall activity with heavy to very heavy showers, are possible over coastal districts of Maharashtra from June 11 to 15. Similar conditions will continue over coastal Karnataka from June 12 to 15. Some parts of Kerala may also experience isolated heavy rainfall until June 15. Besides, Konkan is also in for isolated extremely heavy falls during 12 to 15.
The southwest monsoon is likely to become active from Saturday through Wednesday, therefore, a heavy downpour is expected over Konkan & Malabar coast. The rain totals over the aforementioned places may reach up to 80-100 mm in a day in this time frame.
The maximum temperatures are noted to be below normal across the country excluding Trans Himalayas and South Peninsula region for the next few days. In particular, much of the East and Central regions are expected to witness a decrease in temperatures by 8°C, which is cooler than average in the upcoming days.
Heatwave condition is expected over much of Rajasthan and Semi-arid regions for the rest of this week. The conditions will be limited only to west Rajasthan and part of Gujarat from the early next week onward.
