Southwest monsoon sets in over Kerala

The southwest monsoon has officially arrived in Kerala today, marking an early onset eight days ahead of the usual date of June1. This is the earliest monsoon onset in Kerala since 2009, when it began on May23.

According to historical data since 1975, the earliest recorded onset of the southwest monsoon over Kerala was on May 19 1990, which was 13 days earlier than the normal date.

The advance arrival of the monsoon this year signals the beginning of the rainy season across Kerala, bringing much-needed relief and marking the start of the broader monsoon progression over the Indian subcontinent. Meteorologists will be closely monitoring its movement as it spreads to other parts of the country in the coming weeks.

The IMD has declared a red alert in Kerala for the following districts: Thiruvananthapuram, Kollam, Kottayam, Alappuzha, Thrissur, Idukki, and Malappuram.

 

Coastal Karnataka on red alert

The IMD has forecast heavy rainfall across Karnataka, particularly in the coastal districts, due to a low-pressure area over the east-central Arabian Sea. Extremely heavy rain with gusty winds (30-40 kmph) is expected in parts of Dakshina Kannada, while Udupi and Uttara Kannada districts may see heavy to very heavy rain and widespread moderate showers on Saturday.

Belagavi and Dharwad are also on alert, with moderate rain forecast for several interior districts including Ballari, Bengaluru (Rural and Urban), Chikkaballapura, Chamarajanagara, Tumakuru, and others. On May 25, extremely heavy rain is likely to continue in Dakshina Kannada, Udupi, and Uttara Kannada. Gusty winds will accompany the showers throughout the forecast period, prompting alerts in several districts. IMD advises caution as the weather system develops and moves inland.

Meanwhile, Bengaluru is likely to receive scattered showers over the next five days, the IMD said.
