Now that Hurricane Felix is gone after making landfall in northeast Nicaragua as a category 5 hurricane, my attention has turned to Invest99L. This is a non-tropical low pressure system off the Florida east coast and just northeast of the Bahamas. I was going to post about this system yesterday, but ran out of time during the day, plus the system was not developing all that fast as it was dealing with shear and some dry air.

This morning the area of low pressure still has a low-level exposed circulation with decent deep convection sheared off the to the east of the circulation. It has not changed much since yesterday and a recon flight will fly into the system later today to see if this has become more tropical in nature. If this develops, it could become a problem for the U.S. east coast and could be our my first tropical chase of the season.

I’ll be monitoring throughout the day and will update this afternoon after several hours of visible imagery to look at and possible recon data.
