Re: Looking Around the Basin

As MIke pointed out this a.m., 92L remains just that - a dissorganized weak low. My own observation of visible and RGB satellite this morning seems to indicate a week surface circulation around 17N and 57W, but one not co-located with what appears to be a mid level rotation more to the east ( and north a bit ), around 18N & 54W. Water vapor indicates dry air on the systems west side.

Seems to be a distinct 20-30kt. southerly jet shearing the system. Whether this is part of a large broad closed ULL in the N.E. Carib., or simply a TUTT feature, 200mb charts do not indicate much change in the upper air until possibly 42 hours from now.

Some subtle model tendancies are becoming more evident, but will save such thoughts for the Forecast Lounge.
