South West monsoon hits Kerala
Jun 06 2014 , New Delhi/Thiruvananthapuram
Indian Meteorological Department (IMD) Director General L S Rathore said in New Delhi that "South West monsoon has arrived" after the weather officials studied the rain pattern in Kerala over the last two days.
Rathore said there was "sluggish march" in the onset phase. "We have 13 stations in Kerala and one in Karnataka that have recorded more than 2.5 mm of rainfall over the past two days-- one of the most important criteria to declare its arrival," said Rathore.
Continuous rain for over 48 hours with a westerly windspeed of 15 to 20 knots is among two critical parameters for declaring the arrival of monsoon, which is crucial for the country and its agro-based economy.
After four years of normal and above-normal monsoon, India is expected to have below normal monsoon this year with rainfall projected to be 95 per cent, which will be disappointing for the farming community.
Officials in the weather department had said the monsoon is expected to be below normal because of El-Nino effect, which is generally associated with the warming of ocean water.
Isolated rainfall occurred over Coastal Andhra Pradesh, Rayalaseema, Tamil Nadu, Coastal and South interior Karnataka in the last 48 hours. The South west monsoon, which brings good rainfall to most parts of the country, is a crucial component for agriculture and also for power generation.
Kerala, which depends heavily on hydel power, has been facing severe shortfall in electricity generation, forcing the power board to impose 45-minute loadshedding for domestic consumers since last week.
An IMD bulletin in Thiruvananthapuram said rain occurred at many places in Kerala and Lakshadweep.
Vyttiri and Pookot in Wayanad district received the highest raifall-6 cm each--follwed by Vaikom in Kottayam district (4 cm) and Alappuzha, Ernakulam South, Kudlu (Kasaragod district), Peermade (Idukki district) and Kollam (3 cm each), it said.
Heavy rain or thundershowers would occur at most places in Kerala and Lakshadweep till June 9 morning, it said.
Fishermen have been warned of strong onshore winds from westerly direction, speed occasionally reaching 45-55 kmph, likely off the Kerala coast and over Lakshadweep area during the next 24 hours, the bulletin adds.
According to IMD, last year Kerala received 2570.3 mm rainfall during the South West Monsoon season (June 1 to Sept 30) against the normal rainfall of 2039.6 mm, which was 26 per cent excess.
