DISCUSSION AND OUTLOOK
----------------------
Satellite imagery and radar data from Mexico indicate that Grace 
has made landfall along the coast of Mexico near Tecolutla, Mexico, 
just prior to 100 AM CDT (0600 UTC).  At 100 AM CDT (0600 UTC), the 
center of Hurricane Grace was located just inland near latitude 20.6 
North, longitude 97.2 West. Grace is moving toward the west near 10 
mph (17 km/h) and this general motion is expected to continue 
through this evening. On the forecast track, the center of Grace is 
forecast to farther inland over mainland Mexico today.
 
Maximum sustained winds have increased to near 125 mph (205 km/h) 
with higher gusts. Grace is a category 3 hurricane on the 
Saffir-Simpson Hurricane Wind Scale.  Rapid weakening is expected 
as Grace moves inland over the mountains of central Mexico later 
today.
 
Hurricane-force winds extend outward up to 30 miles (45 km) from
the center and tropical-storm-force winds extend outward up to 150
miles (240 km).
 
The estimated minimum central pressure is 962 mb (28.41 inches).
 
 
HAZARDS AFFECTING LAND
----------------------
Key messages for Grace can be found in the Tropical Cyclone
Discussion under AWIPS header MIATCDAT2, WMO header WTNT42 KNHC and
on the web at www.hurricanes.gov/graphics_at2.shtml?key_messages.
 
STORM SURGE: A dangerous storm surge will raise water levels by as 
much as 6 to 9 ft above normal tide levels along the immediate coast 
within the hurricane warning area near and north of where the center 
is making landfall through early this morning. Near the coast, the 
surge will be accompanied by large and destructive waves.
 
WIND: Hurricane conditions are expected to continue within portions 
of the hurricane warning area in mainland Mexico through early this 
morning. Tropical storm conditions are expected to continue within 
the tropical storm warning area in mainland Mexico through this 
morning.
 
RAINFALL: Grace is expected to produce the following rainfall
amounts:
 
Over Veracruz, Puebla, Tlaxcala, Hidalgo, Queretaro, and eastern San
Luis Potosi...6 to 12 inches of rain with isolated maximum totals of 
18 inches are expected through Sunday. Heavy rainfall from Grace 
will result in significant flash and urban flooding as well as 
mudslides.
 
SURF: High surf generated by Grace will affect the southern Gulf of 
Mexico coastline into the weekend. These swells are likely to cause 
life-threatening surf and rip current conditions.  Please consult 
products from your local weather office.
