Current spell of heavy rainfall likely to continue for three more days

Heavy rainfall in isolated places in State likely

State still has 11 per cent deficit in monsoon rainfall

THIRUVANANTHAPURAM: The monsoon climbed to a vigorous phase over Kerala on Saturday, bringing heavy rainfall in several places, including the hill districts that hold the hydro-electric reservoirs of the State.

A well-marked offshore trough, an ideal atmospheric condition for rain, lay all the way along the West Coast on Saturday promising the continuation of the wet spell. The wind speed across the Kerala coast too has begun touching 45 to 55 km per hour, driving the rain clouds deep inland over the hill districts.

A deep depression over the northwest Bay of Bengal, which crossed West Bengal coast on Saturday evening to move inland in the northwest direction, too is helping the rainfall activity in Kerala by drawing the moisture-laden winds from the Arabian Sea across the peninsula.

The current wet spell in the State could continue for at least three more days, according to the weather models of India Meteorological Department (IMD). The IMD’s regional centre in Chennai, in its bulletin on Saturday, has warned of heavy rainfall in isolated places in the State during this period.

Another low pressure?

The IMD sees indications of another low pressure system forming over the Bay of Bengal. This new system is likely to fall in place over the northwest bay by Tuesday and it too can help rainfall activity in Kerala. The week ahead, thus, holds the promise of bringing down the rainfall deficit for the season in Kerala. As on September 2, the State was 11 per cent deficit in monsoon rainfall, according to the IMD’s latest hydrology update.

During the 24 hours ending at 8.30 a.m. on Saturday, heavy rainfall was recorded in Perinthalmanna (10 cm), Munnar (9 cm), Koyilandy and Kozhikode (8 cm each) and Peerumade and Chittur (7 cm each). The IMD’s rain gauges at more than a dozen other centres, uniformly spread across the State, recorded readings ranging between 6 cm and 2 cm during the period.
