Heavy Rains Likely in Tamil Nadu, Kerala, Telangana from April 26-27

Two troughs, one going from Madhya Pradesh to Tamil Nadu and the other from Interior Maharashtra to Interior Karnataka, are predicted to generate wet conditions across South India this week, according to IMD.

The India Meteorological Department (IMD) has forecast scattered to fairly widespread drizzles, thunderstorms, lightning, and gusty winds across Andhra Pradesh, Telangana, Interior Karnataka, Tamil Nadu, and Kerala over the next three days, from Wednesday & Thursday, April 26-27.

Furthermore, IMD has forecasted significant rainfall (65 mm per day) in isolated areas of Tamil Nadu on Tuesday, Kerala on Tuesday and Wednesday, and Telangana on Thursday. Hailstorms are also possible in several parts of Telangana over the next two days. Raindrops are driven upward into extremely cold parts of the sky, resulting in hailstorms. This causes them to freeze, and when the updrafts can no longer sustain their weight, hail falls.

Given these forecasts, the IMD has issued a yellow warning for all of the aforementioned states during this forecast period. Residents are urged to 'be aware' of the local meteorological situation, according to the advisory. Furthermore, the IMD's regional met centre in Thiruvananthapuram has issued heavy rainfall warnings for Kerala's Idduki and Pathanamthitta districts.

Chennai will likely see moderate rains on Tuesday, while Amravati, Bengaluru, Kochi, Thiruvananthapuram, and Visakhapatnam will see thundershowers all week, and Hyderabad will see thunderstorms on Tuesday, followed by light rains for the rest of the week. Meanwhile, what looked to be a region-wide rainfall deficit for April last week has since evolved into certain southern states posting normalized monthly levels.

Between April 1 and 24, Tamil Nadu (24.6 mm) and Telangana (14 mm) received 'normal' precipitation in comparison to their respective long-term averages, whereas Andhra (20.2 mm) received 'excess' showers. Kerala (27.1 mm) and Karnataka (11.6 mm) have, on the other hand, remained in 'deficit' status this month.
