Gulf of Mexico disturbance; New Orleans levee plan released The
main area of concern today is a tropical wave off of the west
coast of Florida that is kicking off some heavy thunderstorms
over the waters surrounding Key West. Wind shear is low enough
to permit some slow development of this disturbance over the
next day or two as it moves westward or west-northwestward
across the Gulf of Mexico at 10 mph. However, the area of
thunderstorms is of limited size, surface pressures are not
falling, and there are no signs that this area may be a future
threat. Figure 1. Latest satellite image of the Gulf of Mexico.
An upper level low pressure system is spinning over the western
Gulf of Mexico. This low is expected to move ashore over Mexico
by Friday without any tropical development occurring. A tropical
wave that moved through the Lesser Antilles Wednesday is in the
eastern Caribbean. The wave has limited thunderstorm activty,
and there is high wind shear and plenty of dry air in the
eastern Caribbean. Development
