Four to six inches of rain, perhaps more in spots, could fall across Palm Beach County and the Treasure Coast from Tuesday afternoon to late Wednesday as a result of a weather system now in the Caribbean, the National Weather Service said today.
The atmosphere is loaded with water at historic levels, and rain bands could drop 2 to 4 inches over an area in as many hours, meteorologist Dan Gregoria said today from the weather service’s Miami office.
The heaviest rain will be from Tuesday night through Wednesday afternoon.
A flood watch might be issued early Wednesday for coastal urban areas.
Rainfall could be a little less pronounced along the Treasure Coast, but the threat also extends inland over Lake Okeechobee and west to the Gulf of Mexico, Gregoria said.
“We are concerned about heavy rain in a short time,” he said.
And it might not be the end. One to two more waves of saturated atmosphere might move through later in the week.
Thunder and lightning will be isolated, there’s a minimal tornado threat, and whether strong winds accompany the deluge will depend on whether the system develops tropical characteristics before moving over the peninsula, Gregoria said.
The National Hurricane Center’s 2 p.m. tropical weather outlook upped to 40 percent the chance the storm will do just that, and become a tropical depression or Tropical Storm Nicole, by Wednesday afternoon.
A National Science Foundation jet that flew into the system found it did not yet have a well-defined center of circulation, but conditions are favorable for more development, the outlook said.
The outlook mentioned two other systems way out in the Atlantic, but chances were low either will develop into anything in the next 48 hours.
