New Delhi, Mar 13: The Indian Meteorological Department (MeT) has issued warning on a depression over the South Arabian Sea to coastal cities. Heavy to very heavy rainfall is expected between Tuesday and Thursday (March 13 and March 15) in coastal areas of Kerala, Tamil Nadu and in Lakshadweep.

The weather watchdog has advised fishermen to avoid venturing out into the sea for next 48 hours. The depression over southeast Arabian Sea adjoining equatorial Indian Ocean has moved towards north-northwestwards with a speed of about 20 kmph.

The IMD has said wind speed will vary between 40 to 60 kmph and a depression is likely to cause minor damage. The Kerala government has already issued advanced warning to the fishermen and asked coastal villages to be on alert.

Last year, cyclone Ockhi has barrelled into the Lakshwadeep islands after drenching the neighboring states of Kerala and Tamil Nadu. The cyclone left 282 dead and 661 missing in Tamil Nadu and Kerala alone.

The cyclone, which was formed from a low pressure spot in the Bay of Bengal, caused damage worth $4.29 billion to the two southern states.

The India Meteorological Department has classified it as a “very severe cyclonic storm,” a designation for tempests with wind speeds reaching 137 miles an hour.
