SE Coast Low Invest 90L
      #113868 - Fri Jul 23 2021 08:15 AM

An area of more concentrated low pressure along a trof that has moved just offshore overnight and is now located generally east of the Georgia and South Carolina border as of this entry is showing some signs of development this morning, a little ahead of schedule, and so we are starting a lounge on this disturbance.

Invest 90L is expected to drift around off the southeast coast for the next several days over warm waters near and over the Gulf Stream, which is expected to afford it potentially several days with which to further organize.

NHC has been highlighting a chance of development here over the past several days, has now upped its odds to 30% within about 48/72 hours, and this could be conservative.

More details to come. This disturbance has been tagged Invest 90L and the title has been updated accordingly.

Models are mixed right now on this one, but generally keep it weak. GFS doesn't do much, HWRF initial having a hard time hanging on, the 12Euro moves it across central Florida back into the Gulf and eventually into Louisiana. Something to watch over the next couple of days, but unlikely (but not impossible) for something to happen.

The Canadian model (CMC) has it developing and landfalling near GA/FL Border Monday afternoon.

I wonder how the persistent tropical wave making its way under the upper level low north of Hispaniola will will play into this. May all end up in the gulf and get going, the wave may actually find it self in a good spot in a few days near the northern bahamas.

Looking at the latest models on the FSU site, there seems to be a weak consensus on a system moving out to the NE and a much weaker system moving into FL/GA and possibly a very weak low in the NE Gulf. Wait and see time.

I'm watching and ready for something. We need rain in Gulfport even though our neighbors seem to get a bit. So tired of passing thunderstorms "parting" over us. I think it is being on Boca Ciega Bay and the influence of Tampa Bay temperatures doing their impact on what is big for everyone else. Every season, most storms. UGH

This sad looking little low has me excited. Won't be a Laura, but could become an Elsa...

Bring it on! LOL
