Tropical Storm Iota Public Advisory Number 2
2020-11-13 21:44:18| National Hurricane Center (Atlantic)
Issued at 400 PM EST Fri Nov 13 2020 000 WTNT31 KNHC 132044 TCPAT1 BULLETIN Tropical Storm Iota Advisory Number 2 NWS National Hurricane Center Miami FL AL312020 400 PM EST Fri Nov 13 2020 ...DEPRESSION STRENGTHENS INTO TROPICAL STORM IOTA.. ...RISK OF DANGEROUS WINDS, STORM SURGE, AND RAINFALL IMPACTS IN CENTRAL AMERICA BEGINNING SUNDAY NIGHT OR MONDAY... SUMMARY OF 400 PM EST...2100 UTC...INFORMATION ---------------------------------------------- LOCATION...13.8N 74.3W ABOUT 335 MI...540 KM SSE OF KINGSTON JAMAICA MAXIMUM SUSTAINED WINDS...40 MPH...65 KM/H PRESENT MOVEMENT...WSW OR 255 DEGREES AT 3 MPH...6 KM/H MINIMUM CENTRAL PRESSURE...1006 MB...29.71 INCHES WATCHES AND WARNINGS -------------------- There are no coastal watches or warning in effect. Interests in Nicaragua and Honduras should monitor the progress of this system. A Hurricane Watch may be required for a portion of that area tonight or early Saturday. DISCUSSION AND OUTLOOK ---------------------- At 400 PM EST (2100 UTC), the center of Tropical Storm Iota was located near latitude 13.8 North, longitude 74.3 West. Iota is moving toward the west-southwest near 3 mph (6 km/h), and this motion is expected to continue through early Saturday. A westward to west-northwestward motion at a slightly faster forward speed is expected to begin by late Saturday 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 late Sunday and Monday. Maximum sustained winds have increased to near 40 mph (65 km/h) with higher gusts. Steady to rapid strengthening is likely over the weekend, and the system is forecast to be a major hurricane 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 1006 mb (29.71 inches). HAZARDS AFFECTING LAND ---------------------- Rainfall: Through Wednesday morning, Iota is expected to produce 4 to 8 inches of rain, with local 12 inch totals, across portions of northern Colombia, Panama and Costa Rica. Across Jamaica and southern Haiti, 2 to 4 inches are expected, with local amounts up to 6 inches. Across remaining sections of Central America, the system has the potential to produce 20 to 30 inches of rain with a focus across northern Nicaragua and Honduras. This rainfall would lead to significant, life-threatening flash flooding and river flooding, along with landslides in areas of higher terrain. SURF: Swells generated by Iota will begin affecting portions of the coast of Colombia, and the southern coasts of Hispaniola and Jamaica during the next day or so. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office. NEXT ADVISORY ------------- Next complete advisory at 1000 PM EST. $$ Forecaster Brown
