HAZARDS AFFECTING LAND
----------------------
Key messages for Tropical Depression Five can be found in the
Tropical Cyclone Discussion under AWIPS header MIATCDAT5 and WMO
header WTNT45 KNHC.
 
WIND: Tropical storm conditions are expected to reach the coast
within the warning area on Tuesday, making outside preparations
difficult or dangerous.
 
STORM SURGE: The combination of storm surge and 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...
 
High Island, TX to Vermilion/Iberia Parish Line, LA...1-3 ft
 
The deepest water will occur along the immediate coast near and to
the east of the center. 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.
 
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_at5.shtml?peakSurge.
 
RAINFALL: Tropical Depression Five is expected to produce rainfall 
totals of 3 to 6 inches with maximum totals of 9 inches for parts of 
the Upper Texas Coast inland through east-central Texas, with 2 to 3 
inches for Southwest Louisiana. This rainfall could produce flash 
flooding, especially in low-lying and urban areas.
 
For a complete depiction of forecast rainfall associated with 
Tropical Depression Five, please see the National Weather Service 
Storm Total Rainfall Graphic available at
