Last few days Maharashtra is suffering from the heat wave. According to India Meteorological Department (IMD), pre-monsoon showers starting in parts of the state, including Konkan, Madhya Maharashtra, Marathwada and Vidarbha, from Friday. However, the IMD has forecast only isolated rains for these regions due to the intense heating over the last few days.
On Thursday morning, few places of Maharashtra like Konkan and Madhya Maharashtra already received some rainfall. Sangli received 30mm rainfall and 10mm rainfall in Kolhapur, Miraj and Shirur each.
K Sathi Devi, head of the IMD’s National Weather Forecasting Centre, told TOI that only isolated showers have been forecast for regions in Maharashtra as the pre-monsoon season normally does not see widespread rainfall activity in the state. Isolated rains in a region mean that 1% to 25% stations may get rainfall, as per the IMD.
“This is causing spillover of moist air from the systems to travel up to Maharashtra. This, coupled with solar heating, can cause isolated spells in parts of the state till May 15,” she added.
Pre-Monsoon Season is synonymous with heat and humidity with uncomfortable conditions throughout the day and night. However, fairly stronger winds bring down temperatures to a comfortable level during Monsoon in India.
Clouds are more of vertical in nature during the pre-Monsoon season and mostly come up during late afternoon and early evening hours. They are triggered by high temperatures and towering clouds build up. On the other hand, the Monsoon season is known for stratiform clouds, mainly sheet-like continuous layers of clouds. Depths of these clouds are less but the layers are thick and moisture laden.
However, sources from Skymet Weather Services said that the rains in parts of the state have been due to the north-south trough extending from north interior Karnataka to Tamil Nadu. “Now, the north-south trough has shifted and is seen extending from northwest Rajasthan to south Madhya Maharashtra. Hence, scattered rainfall may occur over south Madhya Maharashtra and the adjoining Konkan region for another 24 hours. These scattered showers are likely to cover some more parts of Madhya Maharashtra and Konkan region, with stations like Pune, Nashik, Sangli, Satara, Kolhapur getting some showers,” a Skymet source said.
