tropical update Friday 9-18-20, 7 am

9/18/2020

 
Good morning.

The tropics remain active this morning. Sally made landfall on Wednesday morning as a Cat 2 near Gulf Shores Alabama, between Mobile Bay and the Florida/Alabama state line.

Teddy currently a Cat 4 is heading toward Bermuda and Nova Scotia. It should pass east of Bermuda but could be close. Its too soon to say about Nova Scotia.

The orange X below should become TD #23 soon and should follow in Teddy's wake, out to sea. If you look at the surface map below a prominent window remains between the high pressure just east of Florida and the one in the Central Atlantic. If this persists it should continue to protect the southern 1/2  and east coast of the state of Florida.

If you look at the Infra Red image of Africa below you will see little activity over the continent. The Cape Verde season is almost over. After the current batch we will probably not see many. The Cape Verde season usually ends around the beginning of October.

If you look at Sea Surface Temperature and Ocean Heat Content (influenced by water temps and the depth of the warm water) diagrams below you can see that the next areas to watch will be the Western Gulf of Mexico, where TD #22 is now, and the Western Caribbean. Their season usually starts early October to early November.

Until next time,
