At 700 PM CDT (0000 UTC), the broad disturbance was centered near
latitude 27.9 North, longitude 87.8 West. The system is moving
toward the west-southwest near 8 mph (13 km/h). A motion toward the

Friday and a northwestward motion by early Saturday. On the forecast
track, the system is expected to approach the central U.S. Gulf
Coast this weekend.
Maximum sustained winds remain near 30 mph (45 km/h) with higher
gusts. Strengthening is forecast during the next 72 hours, and the
disturbance is forecast to become a tropical depression early
Thursday, a tropical storm by Thursday night, and a hurricane on
Friday.
Shower and thunderstorm activity has gradually been increasing in
coverage and organization, and the low is expected to become a
tropical depression or a tropical storm on Thursday.

NOAA Hurricane Hunters and surface observations is 1010 mb (29.86
inches).
HAZARDS AFFECTING LAND
----------------------
STORM SURGE:  The combination of a dangerous storm surge and the
tide will cause normally dry areas near the coast to be flooded by
rising waters moving inland from the shoreline.  The water could
reach the following heights above ground somewhere in the indicated
areas if the peak surge occurs at the time of high tide...
Mouth of the Pearl River to Intracoastal City...3 to 6 ft
Surge-related flooding depends on the relative timing of the surge
and the tidal cycle, and can vary greatly over short distances. For
information specific to your area, please see products issued by
your local National Weather Service forecast office.
RAINFALL:  The system is expected to produce total additional rain
accumulations of 6 to 12 inches near and inland of the central Gulf
Coast through early next week, with isolated maximum rainfall
amounts of 18 inches.
Rainfall amounts exceeding 6 to 9 inches have already occurred
across portions of the New Orleans metropolitan area today, which
has resulted in flooding.
WIND:  Hurricane conditions are possible within the Hurricane Watch
area by Friday night, with tropical storm conditions possible by
early Friday.
