DISCUSSION AND OUTLOOK
----------------------
At 100 AM EST (0600 UTC), the center of Tropical Storm Eta was
located near latitude 14.9 North, longitude 80.4 West.  Eta is 
moving toward the west near 13 mph (20 km/h), and this general 
motion is expected to continue through this morning.  A slower 
motion toward the west-southwest is forecast by this afternoon and 
continuing into Tuesday.  On the forecast track, the center of Eta 
is expected to approach the northeastern coast of Nicaragua this 
afternoon, and make landfall within the Hurricane Warning area in 
Nicaragua by early Tuesday.  The center of Eta is forecast to move 
farther inland over northern Nicaragua through early Wednesday.
 
Maximum sustained winds are near 70 mph (110 km/h) with higher
gusts.  Strengthening, possibly rapid, is expected through early 
Tuesday, and Eta is expected to become a hurricane within the next 
few hours. Additional strengthening is likely thereafter, and Eta is 
forecast to be a major hurricane when landfall occurs by early 
Tuesday. 
 
Tropical-storm-force winds extend outward up to 140 miles (220 km)
from the center.
 
The estimated minimum central pressure is 989 mb (29.21 inches).
 
 
HAZARDS AFFECTING LAND
----------------------
Key messages for Eta can be found in the Tropical Cyclone
Discussion under AWIPS header MIATCDAT4 and WMO header
WTNT44 KNHC.
 
WIND:  Hurricane conditions are expected in the Hurricane Warning
area beginning tonight, with tropical storm conditions possible in 
this area by this afternoon.  Tropical storm conditions are expected 
in the Tropical Storm Warning area by this afternoon, and
hurricane conditions are possible in the Hurricane Watch area by 
early Tuesday.  Tropical Storm conditions are possible in the 
Tropical Storm Watch area by early Tuesday.
 
RAINFALL:  Eta is expected to produce the following rainfall amounts
through Friday evening:
 
Much of Nicaragua and Honduras: 15 to 25 inches (380 to 635 mm),
isolated amounts of 35 inches (890 mm).
 
Eastern Guatemala and southern Belize: 10 to 20 inches (255 to 510
mm), isolated amounts of 25 inches (635 mm).
 
Portions of Panama and Costa Rica: 10 to 15 inches (255 to 380 mm),
isolated amounts of 25 inches (635 mm).
 
Jamaica and southeast Mexico: 5 to 10 inches (125 to 255 mm),
isolated amounts of 15 inches (380 mm) over southern areas.
 
El Salvador, Southern Haiti, and the Cayman Islands: 3 to 5 inches
(75 to 125 mm), isolated amounts of 10 inches (255 mm)
 
This rainfall would lead to catastrophic, life-threatening flash
flooding and river flooding, along with landslides in areas of
higher terrain of Central America.  Flash flooding and river
flooding would be possible across Jamaica, southeast Mexico, El
Salvador, southern Haiti, and the Cayman Islands.
 
STORM SURGE:  A dangerous storm surge will raise water levels by as
much as 10 to 15 feet above normal tide levels in areas of onshore
winds along the coast of Nicaragua within the hurricane warning
area, and 3 to 5 feet above normal tide levels along the coast of
Honduras within the tropical storm warning area.  Near the coast,
the surge will be accompanied by large and destructive waves.
 
SURF:  Swells generated by Eta are expected to affect portions of
the coast of Central America and the Yucatan Peninsula of Mexico
during the next few days.  These swells are likely to cause
life-threatening surf and rip current conditions.  Please consult
products from your local weather office.
