NHC Tracking Potential Tropical Storm

July 20, 2010

The National Hurricane Center in Miami is currently tracking a “vigorous tropical wave located over Puerto Rico and the Virgin Islands.” So far the disturbance has produced only “widespread cloudiness and thunderstorms across the northern Leeward Islands, the Virgin Islands, Puerto Rico and adjacent Atlantic and northeastern Caribbean waters,” the NHC said.

The bulletin also noted that “although surface pressures are not falling significantly over the area, recent upper-air data indicate the system is becoming better organized in the middle and upper levels of the atmosphere.”

According to the NHC’s calculations there is a “medium chance, 30 percent, of this system becoming a tropical cyclone during the next 48 hours as the disturbance moves west-northwestward at 5 to 10 mph.”

Even though the odds are against the system developing into a tropical cyclone, it will produce. locally heavy rainfall and gusty winds of 30 to 40 mph, which “could affect the areas indicated above as well as the Dominican Republic, Haiti., Eastern Cuba, the Turks and Caicos Islands and the southeastern Bahamas during the next couple of days.”
