Tropical Storm Bertha 'poorly organized' as its soaks Caribbean
(CNN) — Bertha isn't getting bigger -- and that's good news for those in the Caribbean.
The tropical storm dumped plenty of rain and blew plenty hard Saturday afternoon, but -- according to the National Hurricane Center's 2 p.m. update -- its center was "poorly organized" and it hadn't gained strength all day.
The Miami-based center noted that Bertha was centered about 110 miles west-southwest of San Juan, Puerto Rico, and 150 miles east-southeast of Santo Domingo in the Dominican Republic.
The storm -- which formed Thursday -- had sustained winds of 50 mph, just as it had overnight.
Nor was it expected to gain much more steam, anytime soon: "Little change in strength is expected through Sunday," the hurricane center said.
That's not to say the weather will be calm.
There's a reason, after all, that tropical storm warnings have been issued for Puerto Rico, Vieques, Culebra, the eastern Dominican Republic, southeastern Bahamas, the Turks and Caicos Islands, and the U.S. and British Virgin Islands
Bertha could end up dumping 3 to 5 inches of rain -- and perhaps 8 inches in spots -- by the time it's passed through.
The advisory notes that it likely turn toward the northwest, or more out into the open sea, by Saturday night. It could strengthen a little into Monday, but by then it shouldn't pose much of a threat to land.
The storm was expected to move back toward the ocean and away from the U.S. mainland in the coming days, according to CNN's Chad Myers.
The biggest threat to the United States would be rip currents up and down the East Coast as large waves come ashore.
