inland across portions of the southeast U.S. through Sunday night,
and over the western Atlantic Ocean on Monday.

HAZARDS AFFECTING LAND
———————-
Key messages for Claudette can be found in the Tropical Cyclone
Discussion under AWIPS header MIATCDAT3, WMO header WTNT43 KNHC,
and on the web at
www.hurricanes.gov/graphics_at3.shtml?key_messages.

RAINFALL: Claudette is expected to produce additional rainfall
totals of 3 to 6 inches with isolated maximum amounts of 8 inches
across eastern Alabama, northern Georgia, the Florida Panhandle, and
South and North Carolina. Flash, urban and small stream flooding
impacts as well as new and renewed minor to isolated moderate river
flooding are likely across these areas.

The storm total rainfall is expected to be 5 to 10 inches with
isolated 15 inch totals in southeast Louisiana, southern
Mississippi, southern Alabama, and the western Florida panhandle.

STORM SURGE: The combination of 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…

Cape Lookout, NC to NC/VA Border…1-3 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.

WIND: Tropical storm conditions are possible in the watch area
Sunday night and Monday.

TORNADOES: A few tornadoes are possible this evening and tonight
across southeast Alabama, the western Florida Panhandle, and
southwest Georgia.
