Analysis: Data from CIMSS shows that the multiple areas of vorticity are beginning to congeal, meaning 91L is gradually getting more organized. However, shear is still hampering development (as expected), blowing convection to the east and preventing the “center” from closing…
The area of low pressure that we have been tracking in the Caribbean for the past several days has been designated Invest 91L. Per 18z best track data, 91L was located just off the coast of Honduras. Analysis: Invest 91L,…
Tropical development in the northwest Caribbean and/or Gulf of Mexico is looking likely this weekend going into early next week. Analysis: The broad area of low pressure that formed yesterday over the southwest Caribbean Sea has moved little. The center…
Tropical development in the western Caribbean is looking more likely this weekend going into next week. Analysis: A broad area of low pressure has now formed in the SW Caribbean. The associated convective activity is sporadic and disorganized. Shear has…
Tropical development in the west Caribbean late this week going into next week remains a possibility. Analysis: A broad area of disturbed weather has already formed over the extreme SW Caribbean. However, shear is currently high across much of the Caribbean…
We mentioned back on the 17th that conditions in the Caribbean/Gulf would favor an increase in tropical activity. Long-range model guidance is now picking up on this. The ECMWF (euro), GFS, and UKMET are all in agreement on a broad…
The remnants of Kirk were able to develop a closed center overnight per another ASCAT pass — meaning we now have Tropical Storm Kirk (again). At the 5 AM EDT/AST advisory, Kirk was moving west at 18 mph with 40…
Kirk officially degenerated yesterday morning at the 11 AM EDT/AST advisory. This is because an ASCAT pass revealed that there was no closed center. It appears that fast forward speed and dry air were the cause of dissipation. While…
Those of us who were ready for some fall-like weather this week are going to have to wait. Model guidance has backed off significantly on the idea of a Central/Eastern U.S. trough mid/late week. It looks like a Southeast ridge…
The Atlantic is still very busy in terms of tropical activity. We are monitoring four active systems: Tropical Storm Kirk, the remnants of Tropical Depression 11 (TD 11), Invest 98L, and Invest 90L. We are going to focus on Kirk,…
