Overnight Models For Tropical System That May Impact Gulf!

Just a brief morning update on Invest 93 and what the models showed overnight.

If you look at satellite imagery over the Caribbean this morning, you may think “wow, we have a tropical storm” but these images are creating a false impression. There is a nice area of convection in the Caribbean (area outlined in yellow) but the actual surface low is removed from this deep convection. The surface low is west of the convection (red ‘L’), which means there is shear in the Caribbean. The shear is beginning to lessen up so intensification of the low into a tropical depression or tropical storm is likely.

The National Hurricane Center (NHC) is giving the low an 90% chance of development into a tropical cyclone over the next five days and a 60% chance of development within 48 hours.
