South Peninsular India covering Kerala, Mahe, Tamil Nadu, Puducherry and South Interior Karnataka & Coastal Karnataka are witnessing decent pre-monsoon activity. These showers are moderate in nature and heavy only in very few places. Weather activity with hailstorms in a few places including Bangalore is a little unusual. Lightening strikes, thunderstorms, heavy rains and gusty winds, claiming loss of life and property is rather uncommon. Pre Monsoon storms with intermittent rains will continue till month's end.
Moderate to heavy showers lashed Bengaluru, Chitradurga, Mangalore, Kozhikode, Thiruvananthapuram, Salem, Coimbatore, Ooty and Paramathy. Most locations have crossed their monthly average rainfall. Few locations like Bengaluru received nearly double the normal rainfall. Heavy showers are likely at isolated places over interior Tamil Nadu and border areas of Kerala. Bengaluru, Mysuru, Mandya, Hassan and Chitradurga are also expected to have moderate rainfall.
The seasonal pre monsoon peninsular India trough is quite active. The trough is running through and through the interior parts and oscillates as well. Typical pre-monsoon day temperatures of 36-38°C across the region provide heat triggers. Most of the weather activity occurs later part of the day and early at night.
Pre Monsoon activity will be a regular feature till the monsoon arrives. Rain and thundershowers accompanied by strong winds and lightning necessarily need caution. Heavy rains may result in water logging in the prone areas, more so for the low-lying ones. Stable weather conditions are expected only after the monsoon stream sweeps this region.
