Tuesday, May 17: Karnataka is set to experience intense rainfall activity for a second successive week, as heavy pre-monsoon showers have been forecast across its coastal and southern areas until Saturday (May 21) and possibly beyond.

After Cyclone Asani-induced rains pounding the state last week, a cyclonic circulation over Kerala and a north-south trough running from Maharashtra’s Vidarbha to north Kerala will collectively create more wet conditions over Karnataka and its neighbouring states this week.

Accordingly, the India Meteorological Department (IMD) has predicted fairly widespread to widespread rainfall of light to moderate intensity, along with thunderstorms, lightning and gusty winds across Karnataka for the next five days.

Moreover, isolated locations in its Coastal and South Interior subdivisions are likely to be lashed by heavy to very heavy downpours between Tuesday and Thursday, followed by heavy showers on Friday and Saturday.

In view of these predictions, both the aforementioned subdivisions have been placed under an orange alert for the next three days. The advisory urges residents to ‘be prepared’ for rough weather. The rest of the state will remain on a yellow watch (‘be aware’ of weather situation) in this forecast period.

On a district level, the IMD’s regional met centre in Bengaluru has issued orange alerts over 19 Karnataki districts for Wednesday and Thursday, May 18-19. These include Bellary, Bengaluru Rural, Bengaluru Urban, Chamarajanagar, Chikballapur, Chikkamagaluru, Chitradurga, Dakshina Kannada, Davangere, Hassan, Kodagu, Kolar, Mysuru, Mandhya, Ramnagar, Shimoga, Tumkur, Udupi and Uttara Kannada.

The wet conditions will also bring down the mercury levels in the region. In capital city Bengaluru, the daytime temperatures are likely to range between 26-28°C this week — at least 5°C lower than the average for this time of the year.

Apart from Karnataka, similar heavy rainfall conditions have also been forecast over its neighbouring states of Kerala and Tamil Nadu.

Meanwhile, intense rainfall activity prevailed over parts of Karnataka in the past 24 hours as well. Between Monday and Tuesday mornings, the highest precipitation in the state was recorded at Coastal Karnataka’s Mudubidre (11 cm), Bantwal 11 (cm), Mangluru (9 cm), Karkala (8 cm) and North Interior Karnataka Kelvarkop (8 cm).

In fact, owing to the persistent rain spells since the opening week of May, Karnataka has collectively recorded precipitation worth 73.5 mm between May 1 to 16 — a whopping 188% excess as compared to its average for the period, which stands at 33.1 mm.

If these pre-monsoon rains continue for the next two weeks, chances are they may be immediately followed by the first monsoon showers of the season, especially considering reports of a 5-day-early monsoon onset over South India this year.
