Florida hurricane News Palm Beach County weather

One System Near North Carolina’s Outer Banks, Another Forming East Of Florida.

September 17, 2021 early outlook from the National Hurricane Center.


BOCA RATON, FL ( (Copyright © 2021 MetroDesk Media, LLC) —. Two tropical waves are likely to form into tropical depressions over the weekend, according to forecasters at the National Hurricane Center.

And while the ovals on the map indicate where a system may form, and not necessarily a direction of travel, it appears that Florida needs to pay attention to the red “x” that is between Africa and the southeastern United States. That wave has a 70 percent chance of becoming a tropical depression over the next five days.

The red “x” closer to the United States is just 100 miles south of North Carolina’s Outer Banks. That wave has a 70 percent chance of developing over the next two days.

The next storm names are Odette, Peter and Rose.

This is the early morning update from the National Hurricane Center for Friday, September 17th, 2021:

Tropical Weather Outlook
NWS National Hurricane Center Miami FL
200 AM EDT Fri Sep 17 2021

For the North Atlantic...Caribbean Sea and the Gulf of Mexico:

The Weather Prediction Center is issuing advisories on 
Post-Tropical Cyclone Nicholas, located over Louisiana. 

1. Showers and thunderstorms remain disorganized in association with a 
tropical wave and broad area of low pressure located about 1100 
miles west-southwest of the Cabo Verde Islands.  However, 
environmental conditions are expected to be conducive for 
development during the next few days, and a tropical depression 
could still form over the weekend.  This system is expected to move 
westward to west-northwestward at 15 to 20 mph across the tropical 
Atlantic during the next several days.
* Formation chance through 48 hours...medium...60 percent.
* Formation chance through 5 days...high...70 percent.

2. A broad area of low pressure is located about 100 miles southeast 
of the Outer Banks of North Carolina.  Although the circulation of 
this system has become a little better defined since yesterday, the 
associated showers and thunderstorms remain disorganized and 
located mainly well to the east of the center.   Environmental 
conditions are becoming more conducive for development, and a 
tropical depression is likely to form during the next day or so 
while the system moves northward to north-northeastward off the 
southeast and mid-Atlantic U.S. coasts.   Regardless of development, 
this system could bring high surf to portions of the southeast and 
mid-Atlantic U.S. coasts through this weekend.  Additional 
information on this system, including gale warnings, can be found in 
High Seas Forecasts issued by the NOAA Ocean Prediction Center. 
* Formation chance through 48 hours...high...70 percent.
* Formation chance through 5 days...high...70 percent.

3. Disorganized cloudiness and thunderstorms over the far eastern 
tropical Atlantic are associated with a tropical wave located a few 
hundred miles southeast of the Cabo Verde Islands.  Environmental 
conditions are forecast to be only marginally conducive, and 
development, if any, of this system should be slow to occur over the 
next few days while the system moves west-northwestward to 
northwestward over the far eastern Atlantic.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 5 days...low...20 percent.
