Tropical Depression 16 Now a Remnant Low, Raining Over Central America
Hurricane Season 2008: Tropical Depression 16 (Atlantic Ocean)
Tropical Depression 16 formed off the Honduras coast and never had the change to develop into a tropical storm, much to the relief of Central America's residents. Despite the lack of strong winds, heavy and flooding rains still pose a threat to Honduras, Belize, El Salvador and Guatemala until it dissipates, which is expected to happen by October 18.
The last advisory on Tropical Depression 16 (TD16) was issued by the National Hurricane Center on Wed. October 15 at 11:00 p.m. EDT. At that time, TD16 had sustained winds near 30 mph and was weakening as it moved further inland to the west-southwest. It was located about 40 miles south-southwest of Limon, Honduras and 185 miles east southeast of Monkey River Town, Belize. That's near 15.3 north and 85.9 north. Minimum central pressure was estimated near 1006 millibars.
This system, now diminished to a remnant low pressure area on Oct. 16, is expected to continue producing heavy rainfall (between 4 and 8 inches) over Nicaragua, Honduras, Belize, Guatemala, and the Yucatan peninsula with maximum amounts up to 15 inches total.
The Honduras newspaper, Tiempo Digital on-line, reported on the morning of October 16 that in the city of San Pedro Sula 24 hours of rain from Tropical Depression 16 has caused several rivers to overflow in the northern part of Honduras. Flooding was reported in the communities of Columbus and Atlantis. San Pedro Sula is located in the northeastern part of Honduras, over 50 miles inland from the eastern coast.
This satellite image was captured on October 16 at 14:01 UTC (10:01 a.m. EDT from the Geostationary Operational Environmental Satellite (GOES-12). The ill-defined center of Tropical Depression 16 is over Honduras, in the lower middle part of this image.

Tropical Depression 16 Spread Out Over Northeast Honduras
Tropical Depression 16 is not very organized as of mid-day on October 15, as its broad center is on the coast of northeast Honduras. It is expected to become better organized and may become a tropical storm by October 16 or 17. The entire coasts of Belize and Honduras are under a tropical storm warning.
At 11:00 a.m. EDT on Oct. 15, Tropical Depression 16's (TD16) center was about 75 miles east of Limon, Honduras and 270 miles east of Monkey River Town, Belize. That's near latitude 15.8 north and longitude 84.5 west. TD16 has sustained winds near 30 mph with higher gusts, and is moving west near 5 mph. Estimated minimum central pressure was near 1005 millibars.
NASA's TRMM Satellite Analyzes Rainfall from Space
The image above was made from data captured by the Tropical Rainfall Measuring Mission (TRMM) satellite on Oct. 15 at 1:15 Zulu Time or 9:15 p.m. on Oct. 14 as it passed overhead in space. This TRMM image shows the horizontal pattern of rain intensity within TD16. The center is located near the yellow, green and red areas, which indicate rainfall between 20 and 40 millimeters (.78 to 1.57 inches) per hour. The red area is considered moderate rainfall. The image shows that the rainfall is not organized and circular as it would if the storm were better organized.
TRMM will be watching the rainfall from TD16, as it's expected to produce total rainfall amounts of 4 to 8 inches over northeastern Nicaragua, Northern Honduras, Belize, Guatemala, and the Yucatan Peninsula with maximum amounts up to 15 inches. These rains could produce life-threatening flash floods and mud slides.

Tropical Storm Omar and Tropical Depression 16 Form Near Each Other
Tropical Storm Omar, the 15th tropical depression of the Atlantic Hurricane Season is drenching the Netherlands Antilles Islands in the Caribbean, and strengthening. Meanwhile, Tropical Depression 16 formed west of Tropical Storm Omar.
This visible satellite image of the Atlantic Ocean basin shows Tropical Storm Omar to the lower right, and Tropical Depression 16 to the lower left. It was created on Oct. 14 at 9:48 a.m. EDT from the Geostationary Operational Environmental Satellites GOES-11 and GOES-12, which are operated by the National Oceanic and Atmospheric Administration. The image was created by NASA's GOES Project, located at NASA's Goddard Space Flight Center, Greenbelt, Md.
Tropical Storm Omar is bringing heavy rainfall over the Netherlands Antilles, and tropical storm watches are up for Puerto Rico, the U.S. Virgin Islands, British Virgin Islands, and the extreme eastern Dominican Republic. Portions of the Netherlands Antilles can expect between 4 and 8 inches of rain, with maximum amounts of 12 inches possible. Omar's rains also extend south into northern central Venezuela and the northern Guajira Peninsula. Up to 6 inches of rain from Omar are possible in those areas. All of these rains could produce life-threatening flash floods.
On Oct. 14 at 11:00 a.m. EDT Omar had maximum sustained winds near 40 mph, and was located near latitude 14.0 north and longitude 69.0 west. That's about 355 miles southwest of San Juan, Puerto Rico. Omar is moving southeast near 2 mph, and will turn east then northeast later today. The estimated minimum central pressure is 1001 millibars.
A tropical storm watch may be required later this afternoon for the islands of St. Martin, St. Eustatius and Saba.
Tropical Depression 16 Forms Raining on Honduras
Meanwhile, Tropical Depression 16 (TD16) has formed to the west of Omar, and is located about miles north-northeast of Cabo Gracias a Dios on the Nicaragua/Honduras Border. That's near 15.6 north latitude and 83.0 west longitude. TD 16's maximum sustained winds are near 30 mph and some strengthening is expected during the next couple of days as long as the center of depression remains offshore. That means TD16 could become a tropical storm by Wednesday. Its moving northwest near 7 mph, and will turn west later today. Minimum central pressure was 1004 millibars.
TD16 will bring heavy rains (4 to 8 inches, with isolated amounts up to 15 inches) over parts of Nicaragua, Honduras, and Belize over the next couple of days, and the government of Honduras issued a tropical storm warning from the border between Honduras and Nicaragua, westward to Limon.
