DISCUSSION AND OUTLOOK
At 100 PM EST (1800 UTC), the center of Tropical Storm Iota was
located by an Air Force Reserve reconnaissance aircraft near
latitude 12.6 North, longitude 76.4 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 southwest Caribbean Sea during the next day or
so, and approach the coasts of Nicaragua and northeastern Honduras
Preliminary data from an Air Force Reserve Hurricane Hunter
aircraft indicate that the maximum sustained winds are near 50
mph (85 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 1002 mb (29.59 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
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 possible within the Hurricane
Warning area by late Monday, with tropical storm conditions
possible by Monday afternoon. Tropical storm conditions are
expected to begin on the islands of San Andres and Providencia
late Sunday. Hurricane conditions are possible on Providencia by
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.
