Rafael fades, NHC tracks Caribbean disturbance
Now that Tropical Storm Rafael has faded to what AccuWeather calls ” a shredded zone of downpours and thunderstorms,” can we look forward to a week of a no-drama Atlantic and the Caribbean?
According to National Hurricane Center forecastersa broad area of low pressure will likely form over the southwestern Caribbean Sea in a few days with a low chance of development late this week, and they’re tracking a tropical wave in the central Caribbean that’s bringing heavy showers and thunderstorms across Puerto Rico and Hispaniola. More showers are hitting the southwest and far northwest Caribbean.
Some moisture from Rafael joined a slow-moving front to dump 1 to 8 inches of rain in parts of eastern Texas and Louisiana Sunday. Some or most of the rest will be drawn northward into the central Gulf Coast region this week to bring downpours to Louisiana, Alabama and parts of Georgia, AccuWeather meteorologist Grady Gilman said, as part of a cold front moving over the lower Mississippi Valley.
But the season isn’t over yet.
“Once again, just as with Rafael most recently, the western and central part of the Caribbean Sea will be conducive for tropical depression and storm formation, provided that moisture increases over the region, wind shear remains low and there is a clustering of showers and thunderstorms in the first place,” AccuWeather said, adding that the zone of wind shear north of the Caribbean that has been blocking development could dissolve during the third week of the month.
The remnants of Rafael are expected to dissipate by Tuesday night as it continues to meanders around the Gulf.
The next named storm of the Atlantic Hurricane season will be Sara.
Here’s the latest update from the NHC as of 6 a.m. CST Monday, Nov. 11:
National Hurricane Center map: What else is out there and how likely are they to strengthen?
Systems currently being monitored by the National Hurricane Center include:
Western Caribbean Sea: A broad area of low pressure is expected to form over the western Caribbean Sea during the next couple of days.
Environmental conditions appear conducive for some gradual development of this system thereafter, and a tropical depression could form late this week or this weekend while moving slowly westward.
- Formation chance through 48 hours: Low, near 0 percent.
- Formation chance through seven days: Medium, 40 percent.
What do the colored areas on the NOAA map mean?
The hatched areas on a tropical outlook map indicate “areas where a tropical cyclone — which could be a tropical depression, tropical storm or hurricane — could develop,” said National Hurricane Center Deputy Director Jamie Rhome.
The colors make it visibly clear how likely a system could develop with yellow being low, orange medium and red high.
The National Hurricane Center generally doesn’t issue tropical advisories until a there is a named storm, but there is an exception.
“If a system is near land and there is potential for development, the National Hurricane Center won’t wait before it issues advisories, even if the system hasn’t become an actual storm. This gives residents time to prepare,” Rhome said.
