The period between 16th August and 25th September, 2018 will be very hot and far above normal temperatures upset normal life. Cyclones/ Thunderstorms with squally winds at isolated places are forecast.

With a change in the weather pattern after 24th October, 2018 possibility of a Cyclone in the Arabian Sea between 24th October and 30th October, 2018 is forecast. This cyclone will be weak but will yield good rainfall and likely to cross the coast between Mahe and Mangalore around 28th October, 2018. This system will continue to travel inland and dump heavy to very heavy rainfall between 31st October and 3rd November 2018.

The period between 31st October and 26th November, 2018 will witness squally winds with thunderstorms. During this period winter will set in and the night temperatures will be near normal. But fairly wide spread rainfall is also forecast. While Southern districts of Tamilnadu, Kerala get heavy to moderate rainfall, moderate in Central and light rain in North Tamilnadu is forecast. There is sure possibility of a severe cyclone during the above period.

Important dates of cyclone/ thunderstorm activity:
(1)Between 5th November & 10th November, 2018, (around Nagapattinam)
(2) Between 13th November & 18th November, 2018, (Severe cyclone around Nagapattinam) and

(5)Look for a Cyclone between 29th December, 2018 and 1st January, 2019. This system will cross the coast between Tuticorin and Tondi.

My sincere efforts have gone into preparing this forecast. Year on year I am learning and showing quality improvement on the dependability of my LONG RANGE SPECIFIC WEATHER forecast. My request to our Government and the general public of Southern peninsula is that, they should take serious measures to save whatever rain water we are getting between third week of August, 2017 and end of December, 2017. Though moderate rainfall is forecast before the end of March, 2018, it will not be sufficient to meet the demand of subsequent months. Moreover adding to the water crisis the ‘Extreme Summer between April and end of June, 2018 will cripple normal life. We can reduce the hardship little bit if our government advises/Orders all the Educational institutions to conduct exams before the end of March, 2018 and declare vacations.
