ST. THOMAS - A low pressure system sitting over the territory will dump 3 to 5 inches of rain on the Virgin Islands by midday today.
Winds should not be unusually high, and the system is not likely to develop into an organized storm system before it moves on to Puerto Rico and the Dominican Republic later this week, according to Luis Rosa, a meteorologist with the National Weather Service in San Juan.
The weather service has issued a small-craft advisory, because winds of up to 20 knots are expected in the offshore waters, Rosa said.
The rainfall likely will put the Virgin Islands above average totals for the month of September, following a wet summer, Rosa said.
The islands of St. Thomas and St. Croix are both above average in terms of rainfall totals for the year-to-date, after suffering an unusually dry spring. St. Thomas received 7.69 inches in the month of August, or 4 inches above the month's average, and has exceeded year-to-date average totals by about 1 inch. St. Croix, which received 4.63 inches during August, or 1.48 inches above the month's average, has also exceeded yearly rainfall totals by 1 inch, Rosa said.
The low pressure system was predicted to hit the Virgin Islands late Tuesday and last through the middle of today, Rosa said.
Because of the increased amount of expected rainfall, the National Weather Service issued a flash flood watch for the Virgin Islands through 6 p.m. Friday. A flash flood watch means that conditions are favorable for heavy rain across the watch area, which may lead to flooding.
"Basically, you are going to receive the month's average of rainfall in the next couple of days," Rosa said Tuesday.
The system may try "to reorganize into a tropical cyclone" by the time it reaches Hispanola, but there only was a 30 percent chance of it developing into a tropical cyclone on Tuesday, Rosa said.
Rosa also said that presently there were no other systems or invests that could affect the Virgin Islands being monitored by the National Weather Service. "There are no other areas of concern at this time," he said.
