Days of heavy rainfall before the scheduled South West Monsoon

… and unusual blossoms.

The South West monsoon which hits Kerala is scheduled to begin in 1st June or end of May. A map of this year’s monsoon by the Indian Meteorological Department is given below.
 
The website of the Indian Meteorological Department is very interesting and informative.

This year the season rainfall from 1 March to 20 May was much higher than the normal rainfall in all the districts of Kerala. Thiruvananthapuram district recorded 598.1mm of rainfall . The normal rainfall during this period is 277 mm. The percentage departure is 116% -an excess

Last year in 2014 the premonsoon rainfall was normal in all the districts of Kerala except in Thiruvananthapuram and Wynad which showed an excess percentage of departure.

The excess rainfall in all the districts of Kerala, this year has brought flooding of rainwater into homes. Many roads and streets are still waist-deep with water. There is coastal erosion causing  havoc to human life, much before the scheduled monsoon.

The laterite soil sprung some wonders after the first heavy downpour.

Where did the bulbs come from ? 
There was a surprise from an old coconut tree. An Ipomea growing from within its narrow hollow gave forth blossoms. The lichens still linger on the old coconut trees.
