DISCUSSION AND OUTLOOK
----------------------
At 700 PM EST (0000 UTC), the center of Tropical Storm Iota was
located near latitude 12.6 North, longitude 76.9 West. Iota is
moving toward the west-southwest near 7 mph (11 km/h). A westward
motion with some increase in forward speed is expected to begin very
soon and continue through Monday night. On the forecast track, Iota
will move across the southwest Caribbean Sea tonight and Sunday,
pass near or over Providencia island on Monday and approach the
coasts of Nicaragua and northeastern Honduras Monday afternoon or
evening.
 
Maximum sustained winds are near 60 mph (95 km/h) with higher
gusts.  Steady to rapid strengthening is expected during the next
day or two, 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 105 miles (165 km)
from the center.
 
The estimated minimum central pressure is 995 mb (29.39 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:  Hurricane conditions are expected on the island of
Providencia by late Sunday night with tropical storm conditions
expected beginning Sunday evening. Hurricane conditions are
possible within the Hurricane Watch area in Nicaragua and
Honduras by late Monday, with tropical storm conditions possible by
Monday afternoon. Tropical storm conditions are expected to begin
on the island of San Andres late Sunday or Sunday night with
hurricane conditions possible there Sunday night or early Monday.
 
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.
