HAZARDS AFFECTING LAND
----------------------
Key messages for Elsa can be found in the Tropical Cyclone
Discussion under AWIPS header MIATCDAT5, WMO header WTNT45 KNHC and

WIND: Tropical storm conditions are expected in the Tropical Storm
Warning area along the Georgia coast by late today or tonight and
along the South Carolina coast tonight and early Thursday.
Tropical storm conditions are possible in the watch area in the
mid-Atlantic and northeastern states by Thursday night and Friday.
 
STORM SURGE: The combination of a 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...
 
Suwannee River to Aucilla River...1 to 2 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: Elsa is expected to produce the following rainfall amounts
and impacts the rest of this week:
 
Across northern portions of the Florida Peninsula...additional 1 to
3 inches through tonight, with storm total amounts of 4 to 8 inches.
Localized maximum storm totals up to 12 inches across southwest
Florida.  Additional heavy rainfall may result in considerable
flash and urban flooding, along with continued rises to minor and
isolated moderate flood.
 
Across portions of southeast Georgia and the Lowcountry of South
Carolina, 3 to 5 inches with isolated maximum totals up to 8 inches
will be possible this evening into Thursday, which may result in
considerable flash and urban flooding.
 
Across central and eastern North Carolina into southeastern
Virginia...1 to 3 inches with isolated totals up to 5 inches tonight
through Thursday night, which could lead to limited flash and urban
flooding.
 
Across the Northeast and New England, 1 to 3 inches with isolated
totals up to 5 inches Thursday into Friday will be possible.  This
could lead to limited flash and urban flooding.
 
TORNADOES: A few tornadoes are possible through tonight across
northern Florida and southeastern Georgia into eastern South
Carolina.  The tornado threat should move into the eastern
Carolinas and parts of the Mid-Atlantic Coast on Thursday.
