Caribbean weather system could make the first week of school all wet

That damp, dreary feeling most kids have for heading back to school? That’s how South Florida could look this week from the first of two weather systems approaching.

There’s a low pressure trough near the southeastern Bahamas that the National Oceanic and Atmospheric Administration’s 8 a.m. advisory says is bringing showers and thunderstorms. Though given only a 10 percent chance to form into a serious storm over the next two days and 40 percent over the next five days, South Florida should still feel more than the usual precipitation from it.

The National Weather Service predicts storms that will bring “at least to 2 to 4 inches of rain this week, with locally heavier amounts. This may be sufficient to cause local flooding problems. There is a reasonable threat of minor flooding of streets and poor drainage areas.” The wet weather is expected to start on Tuesday and last through the weekend.

In other words, Miami Beach, don’t put those weekend kayaks away just yet.

The NOAA describes the other system as being “a large area of showers and thunderstorms located about 800 miles east-northeast of the northern Leeward Islands” with a surface trough combining with an upper level low. It gives the system zero chance of formation:

“Upper-level winds are not conducive for development of this system while it moves northwestward over the central Atlantic at 10 to 15 mph.”
