Not much of a lull. Ida and Julian are next

A broad area of low pressure is forecast to form over the western
Caribbean Sea late this week. Environmental conditions are expected
to be favorable for gradual development of this system thereafter
while it moves west-northwestward over the northwestern Caribbean
Sea.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...low...20 percent.

GFS last night! ?88CC449E-68B3-4204-9E25-21E8A9549D44.pngECD22FAA-7E29-4150-B57E-5BE99E1978E6.png
 
Last week, the Nino 3.4 anomaly cooled from -0.4 C to -0.9 C. That’s bad news if one doesn’t want an active 2nd half of hurricane season and the related increased threat to the SE US.
 
A tropical wave located over the eastern Caribbean Sea is expected
to form a broad area of low pressure over the southwestern Caribbean
Sea by late week. Thereafter, environmental conditions are forecast
to become favorable for gradual development while the system moves
west-northwestward over the northwestern Caribbean Sea.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...medium...40 percent.

I wonder how this current/upcoming steering pattern will affect the SE coast during peak season. Hopefully storms will have enough wiggle room to escape quietly out to sea.
It looks like we’re setting up the pattern the Webb and others have been talking about evolving all summer. A pattern that blocks off the OTS path and steers storms into the SE coast.
