Weather Blog: Widespread weakening in the tropics

Posted: Sep 16, 2018 6:53 PM -04:00 Updated:

Only a few days ago there were four named storms in the Atlantic. On Monday, there may not be any.

 

 The area with the most interest to us in Southwest Florida is the remnants of Isaac, which are moving over Jamaica on Sunday. Strong wind shear that tore apart Isaac in the first place is still working to keep the system from organizing again. At this point, it seems unlikely that it could become more than a weak depression if anything. The National Hurricane Center only gives the remnants of Isaac a 20 percent chance to reorganize.

Much of the moisture with Isaac's remains will track into the Yucatan Peninsula of Mexico later in the week. That moisture will stay south of Florida and won't have a noticeable impact on our weather.

Elsewhere, Florence is now a tropical depression and will turn northeast on Monday as it dissipates. The unrelenting rain will finally let up on Monday in the Carolinas. River flooding, however, will likely last for weeks. Landslides and additional flooding could impact the Appalachian mountains from North Carolina into the Virginias from the remnants of the storm.

On the other side of the Atlantic, Helene transitioned into a non-tropical system as it passed over the Azores islands. Not far behind it, Joyce weakened to a tropical depression and will begin to circle south over the next day or so. Strong wind shear is also affecting Joyce, and it could dissipate as early as Monday.

There's still 2 and a half months to go in hurricane season. No matter what the rest of 2018 brings, the First Alert Hurricane Tracking Team has you covered.
