Heavy Downpour in one hour on October 8 in Parts of Goa - Posted October 9, 2014

Retreating Monsoon unleashed the heaviest downpour of the month so far this year on October 8, 2014 when Panaji recorded 37.2 mm followed by Quepem with 26 mm and Margao with 23.4 mm. Almost all the rain fell between 10.30 am and 11.30 am and was accompanied by lightening and thunder. Surprisingly barring  Sanguem (16.2 mm) and Dabolim (12.8 mm) all other places in Goa experienced Nil or just traces of rainfall. Mormugao which is within 5 km radius of Dabolim received just traces. Sunshine prevailed over rest of the state throughout the day.

This behaviour is typical of retreating of monsoon this time of the year. However IMD Goa has attributed this rain to the effect on wind flow due to the developing Cyclone Hudhud in Bay of Bengal! IMD Goa Official quoted in Times of India

Such short showers accompanied by thunder and lightening in isolated parts of Goa are expected to continue till October 12, after which the monsoon withdrawal from the state should be a hastened one.

As on today October 9, the Tropical Cyclone is rapidly intensifying and is expected to make landfall near Andhra-Odisha border between October 11 and 12 as a severe storm.

However its effect on Goa could be limited to overcast skies and scattered showers from 10th to 12th October. The Direction the wind will take will determine the extent of the impact in Goa.
