Though the rainfall in the country was reported to be 23 percent deficient last week, the frequent wet spells in Goa have ensured that the rainfall distribution is above normal in both districts of the state. North Goa district received 24 percent rainfall while south Goa recorded 22 percent. “As per met department convention, a rainfall of +19 to -19 percent is considered normal,” K V Singh, director, meteorological centre, Panaji said.
A total rainfall of +20 percent or more is considered excess while -20 to -59 percent is considered deficient. The total seasonal rainfall after the monsoon advanced over Goa on June 6, 2012 has now crossed 1525.7mm (more than 60 inches). “The rainfall received so far is above normal,” Singh said. The offshore trough in Arabian Sea has weakened during the last fornight and the quantum of rainfall has accordingly decreased. But Goa’s monsoon season extends from June to September.
In 2011 season, the total seasonal rainfall had crossed 100 inches on September 1, 2011. A seasonal rainfall of 80 inches and above is considered normal, but for the past few years the state has recorded higher amount of rainfall.
