DISCUSSION AND OUTLOOK
----------------------
At 1000 AM EST (1500 UTC), the center of Tropical Storm Iota was
located near latitude 12.7 North, longitude 76.2 West. Iota is
moving toward the west-southwest near 5 mph (7 km/h).  A westward
motion with some increase in forward speed is expected to begin
later today and continue through Monday. On the forecast track, Iota
will move across the central Caribbean Sea during the next day or
so, and approach the coasts of Nicaragua and northeastern Honduras
on Monday.
 
Maximum sustained winds are near 40 mph (65 km/h) with higher gusts.
Steady to rapid strengthening is likely to begin tonight or 
Sunday, and Iota is forecast to be at or near major hurricane 
strength when it approaches Central America.
 
Tropical-storm-force winds extend outward up to 90 miles (150 km)
from the center.
 
The estimated minimum central pressure is 1006 mb (29.71 inches).
 
 
HAZARDS AFFECTING LAND
----------------------
Rainfall:   Iota is expected to produce the following rainfall
accumulations through Thursday:
 
Honduras, northern Nicaragua, eastern Guatemala, southern Belize: 8
to 16 inches (200 to 400 mm). Isolated maximum totals of 20-30
inches (500 to 750 mm) will be possible, especially from northeast
Nicaragua into northern Honduras.
 
Costa Rica, Panama, and northern Colombia: 4 to 8 inches (100 to 200
mm), with isolated maximum totals of 12 inches (300 mm).
 
This rainfall would lead to significant, life-threatening flash
flooding and river flooding, along with mudslides in areas of higher
terrain.
 
El Salvador, southern Nicaragua and southern Honduras: 2 to 4 inches
(50 to 100 mm), with isolated maximum totals of 6 inches (150 mm).
 
Jamaica: 1 to 3 inches (25 to 75 mm)
 
Wind:  Tropical storm conditions are expected to begin on the
islands of San Andres and Providencia late Sunday.
 
SURF:  Swells generated by Iota will affect portions of the coast of
Colombia, and the southern coasts of Hispaniola and Jamaica during
the next day or two.  Swells will begin to reach the coasts of
Nicaragua and Honduras on Monday.  These swells are likely to cause
life-threatening surf and rip current conditions.  Please consult
products from your local weather office.
