NWS National Hurricane Center Miami FL
200 AM EDT Fri Sep 7 2018

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

The National Hurricane Center is issuing advisories on Hurricane
Florence, located over the central Atlantic Ocean. The Weather
Prediction Center is issuing advisories on Tropical Depression
Gordon, located over Arkansas.

1. Shower and thunderstorm activity associated with an area of low
pressure centered about 500 miles west of the Cabo Verde Islands has
become a little more concentrated over the past couple of hours, but
recent satellite data show that this system is still fairly broad
and elongated.  Environmental conditions appear conducive for
development, and a tropical depression is expected to form within
the next day or so while the system moves slowly westward across the
tropical Atlantic Ocean.
* Formation chance through 48 hours...high...90 percent.
* Formation chance through 5 days...high...90 percent.

2. Showers and thunderstorms have increased in association with a
tropical wave and accompanying low pressure system near the west
coast of Africa.  Environmental conditions appear conducive for
development, and a tropical depression or tropical storm is likely
to form later today or over the weekend while the wave moves
westward or west-northwestward over the far eastern tropical
Atlantic Ocean. Interests in the Cabo Verde Islands should monitor
the progress of this system, and advisories on a potential tropical
cyclone or tropical depression could be issued later today.
* Formation chance through 48 hours...high...80 percent.
* Formation chance through 5 days...high...90 percent.
