CURRENT TROPICAL CYCLONES:
Tropical Cyclone 31L (Iota)…is located 25 miles northeast of El Papalon, El Salvador
Atlantic Ocean:
A non-tropical area of low pressure could form between the Bahamas and Bermuda by early next week.
The system could gradually develop subtropical characteristics through the middle of next week while it moves northeastward.

Tropical Cyclone 31L (Iota)
IOTA MOVING OVER SOUTHERN HONDURAS TOWARDS EL SALVADOR…THREAT OF CATASTROPHIC FLASH FLOODING AND MUDSLIDES CONTINUES ACROSS PORTIONS OF CENTRAL AMERICA
Here’s what the
computer models are showing
According the NHC
advisory 19A…Iota is moving toward the west near 12 mph (19 km/h), and a westward to west-southwestward motion is expected through today.
On the forecast track, the center of Iota will move across portions of southern Honduras and El Salvador before the system dissipates later today.
Maximum sustained winds are near 40 mph (65 km/h) with higher gusts. Rapid weakening is forecast, and Iota should weaken to a tropical depression later this morning and degenerate into a remnant low pressure area by this afternoon.
Tropical-storm-force winds extend outward up to 185 miles (295 km) from the center, mainly along the coast in the Tropical Storm Warning area.
Recent satellite-derived wind data indicate that tropical-storm-force wind gusts are still occurring along the northwestern coast of Honduras.
HAZARDS AFFECTING LAND
WIND: Strong winds are occurring near the center of Iota and these winds will spread farther inland across northern Nicaragua during the next several hours. Tropical storm conditions are occurring in the Tropical Storm Warning areas in Nicaragua and Honduras.
RAINFALL: Iota is expected to produce the following rainfall accumulations through Thursday:
Honduras, northern Nicaragua, southeast and central Guatemala and southern Belize: 10 to 20 inches (250 to 500 mm), with isolated maximum totals of 30 inches (750 mm).
El Salvador and Panama: 4 to 8 inches (100 to 200 mm), with isolated maximum totals of 12 inches (300 mm).
This rainfall will lead to significant, life-threatening flash flooding and river flooding, along with mudslides in areas of higher terrain.
Southern Nicaragua and Costa Rica: 3 to 5 inches (75 to 125 mm), with isolated maximum totals of 10 inches (250 mm).
SURF: Swells generated by Iota will affect much of the coast of Central America and the Yucatan Peninsula during the next day or so. These swells are likely to cause life-threatening surf and rip current conditions.
>>> A broad area of low pressure could form in a day or so over the southwestern Caribbean Sea. Environmental conditions do not appear to be as conducive for development as previously thought, but slow development is possible over the next several days while the system moves slowly westward or west-southwestward across the southwestern Caribbean Sea.
Regardless of tropical cyclone formation, areas of heavy rain are possible during the next several days from Nicaragua southward across Central America and into Colombia. These rains could cause new flooding concerns, especially across previously inundated areas.
