DISCUSSION AND OUTLOOK
----------------------
At 400 PM CDT (2100 UTC), the center of Hurricane Francine was
located near latitude 29.2 North, longitude 91.5 West. Francine is
moving toward the northeast near 17 mph (28 km/h). This general
motion should continue through this afternoon, and Francine is
anticipated to make landfall in Louisiana within the warning area
in the next few hours. After landfall, the center is expected to
cross southeastern Louisiana tonight, then move northward across
Mississippi on Thursday and Thursday night.

Reports from an Air Force Reserve Hurricane Hunter aircraft 
indicate that maximum sustained winds are now near 100 mph      
(155 km/h) with higher gusts.  Little change in strength is 
expected before landfall. Francine is expected to rapidly weaken 
after landfall, and the system is forecast to become post-tropical 
Thursday night or Friday.

Hurricane-force winds extend outward up to 40 miles (65 km) from the
center and tropical-storm-force winds extend outward up to 140 miles
(220 km). An oil platform southeast of the center recently
reported sustained winds of 79 mph (127 km/h) and a peak gust of
93 mph (150 km/h) at an elevation of 82 ft (25 m).  The National
Ocean Service station at Eugene Island, Louisiana, recently
reported sustained winds of 76 mph (122 km/h) and a wind gust of   
99 mph (159 km/h).

The estimated minimum central pressure based on Hurricane Hunter 
aircraft data is 972 mb (28.71 inches).


HAZARDS AFFECTING LAND
----------------------
Key messages for Hurricane Francine can be found in the Tropical
Cyclone Discussion under AWIPS header MIATCDAT1 and WMO header
WTNT41 KNHC.

WIND:  Hurricane conditions are spreading into the hurricane
warning area, with tropical storm conditions already ongoing. 
Hurricane conditions are possible in the hurricane watch area this 
evening and tonight.

Tropical storm conditions are expected in the warning area along
the coasts of Louisiana, Mississippi, and Alabama this evening and
tonight.

RAINFALL: Francine is expected to bring storm total rainfall of 4 to
8 inches, with local amounts to 12 inches across southeastern
Louisiana, Mississippi, far southern Alabama and the Florida
Panhandle through Thursday night. This rainfall could lead to
considerable flash, urban and river flooding.

For a complete depiction of forecast rainfall associated with
Francine, please see the National Weather Service Storm Total
Rainfall Graphic, available at
hurricanes.gov/graphics_at1.shtml?rainqpf and the Flash Flood Risk
graphic at hurricanes.gov/graphics_at1.shtml?ero.  For a list of
rainfall observations (and wind reports) associated this storm, see
the companion storm summary at WBCSCCNS1 with the WMO header ACUS41
KWBC or at the following link:
www.wpc.ncep.noaa.gov/discussions/nfdscc1.html.

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...

Burns Point, LA to Port Fourchon, LA...5-10 ft
Port Fourchon, LA to Mouth of the Mississippi River, LA...4-7 ft
Mouth of the Pearl River, LA to Ocean Springs, MS...4-6 ft
Lake Pontchartrain...4-6 ft
Ocean Springs, MS to MS/AL Border...3-5 ft
Intracoastal City, LA to Burns Point, LA...3-5 ft
Lake Maurepas...3-5 ft

The deepest water will occur along the immediate coast near and to
the east of the landfall location, where the surge will be
accompanied by large and dangerous waves.  Surge-related flooding
depends on the relative timing of the surge and the tidal cycle, and
can vary greatly over short distances.  Storm surge is not expected
to pose a threat to the risk reduction system levees.  However,
there may be some overtopping of local levees.  For information
specific to your area, please see products issued by your local
National Weather Service forecast office.

For a complete depiction of areas at risk of storm surge inundation,
please see the National Weather Service Peak Storm Surge Graphic,
available at hurricanes.gov/graphics_at1.shtml?peakSurge.

TORNADOES:  A few tornadoes are possible through tonight across
parts of southeast Louisiana, southern Mississippi, southern
Alabama, and the Florida Panhandle. On Thursday, the tornado risk
will move into additional parts of Alabama, southwest Georgia and
the Florida Panhandle.

SURF:  Swells generated by Francine are affecting much of the
northern and northwestern Gulf Coast, likely causing
life-threatening surf and rip current conditions. Please consult
products from your local weather office.
