Tropics:

  1. 99L- A wave moving across the Caribbean Sea has a high chance of development over the next 5 days as the system moves WNW. A tropical depression could form late this week/weekend. Then, models show it moving into the Gulf by the weekend. The latest Euro and GFS runs showing this system impacting TX/LA early next week but staying away from us in Florida. Next name on the list is Ida, then Julien.
  2. 98L - A wave over the Eastern Atlantic has a low chance of development due to strong upper-level winds.
  3. 97L - A broad trough in the Central Atlantic has a high chance of formation and a tropical depression could form late this week/weekend. Regardless of development, the GFS and Euro keep this system away from the US.
