HAZARDS AFFECTING LAND
----------------------
Key messages for Tropical Depression Eight can be found in the
Tropical Cyclone Discussion under AWIPS header MIATCDAT3 and WMO
header WTNT43 KNHC.
  
WIND:  Tropical Storm conditions are expected in the warning area 
by Friday night or Saturday morning.  Tropical storm conditions are 
possible within the watch area by Friday night or Saturday morning.
 
RAINFALL:  The tropical depression is expected to produce 3 to 5 
inches of rain with isolated maximum totals of 10 inches through 
Monday along the Gulf Coast of the United States from Louisiana to 
south Texas, and inland to the Mexican states of Coahuila, Nuevo 
Leon, and northern Tamaulipas.  This rain may result in 
life-threatening flash flooding, rapid rises on small streams, and 
isolated minor-to-moderate river flooding.
 
SURF:  Swells generated by the tropical cyclone are expected to 
increase and affect much of the Texas and Louisiana coasts in a day 
or two.  These swells are likely to cause life-threatening surf and 
rip current conditions.  Please consult products from your local
weather office.
