92L and GOM

92L- the system NE of the Leeward Islands yesterday fizzled out.
However... the mid level IR vortice signature is still present and the main convection is now over the Northern Leeward Islands.
The latest satellite imagery is showing high thin cirrus over the Northern Leeward Islands. Indicating No appreciable wind shear at this time. The outflow 'fingers' also would indicate high pressure over or near to the system leading to a more favorable area for possible intensification.
Whether this system is named, numbered or the like. It is still important to keep a frequent check on it.
That said, watch both the convective area and the Mid Level Vortice. As they appear to have split and these often will spin down to the surface at a later time... and closer to the SE U.S.
Reference TD10 of 2005. Split and part of the TD10 signature became Katrina. While this scenario is not likely. Prior systems have been dropped from NHC and NRLMY sites only to be reposted later.

90L GOM
Present satellite imagery indicate a possible Near-to-Surface Low forming in the Middle/ Western Gulf of Mexico. (see attachment)
Centered near 25N/ 91W.
System appears to be elongated from the NE to the SW.
Current surface analysis would indicate a postion closer to 25N/ 92W.

Lowest surface pressures are in the Western GOM and present wind speeds are under 18 knots with max gusts at 23 knots.

91L Area east of the Lesser Antilles.
As of 10AM EDT Monday. NHC has posted a possible NOAA Research mission into this wave on the 13th at 00Z or 8PM EDT on the 12th.
