Tropical Depression Iota Public Advisory Number 20
2020-11-18 09:38:10| National Hurricane Center (Atlantic)
Issued at 300 AM CST Wed Nov 18 2020 000 WTNT31 KNHC 180838 TCPAT1 BULLETIN Tropical Depression Iota Advisory Number 20 NWS National Hurricane Center Miami FL AL312020 300 AM CST Wed Nov 18 2020 ...IOTA WEAKENS TO A TROPICAL DEPRESSION OVER EL SALVADOR... ...THREAT OF CATASTROPHIC FLASH FLOODING AND MUDSLIDES WILL CONTINUE ACROSS PORTIONS OF CENTRAL AMERICA... SUMMARY OF 300 AM CST...0900 UTC...INFORMATION ---------------------------------------------- LOCATION...13.7N 88.3W ABOUT 20 MI...35 KM NW OF EL PAPALON EL SALVADOR ABOUT 55 MI...90 KM E OF SAN SALVADOR EL SALVADOR MAXIMUM SUSTAINED WINDS...35 MPH...55 KM/H PRESENT MOVEMENT...WSW OR 255 DEGREES AT 13 MPH...20 KM/H MINIMUM CENTRAL PRESSURE...1007 MB...29.74 INCHES WATCHES AND WARNINGS -------------------- CHANGES WITH THIS ADVISORY: The Tropical Storm Warning for the northern coast of Honduras has been discontinued. SUMMARY OF WATCHES AND WARNINGS IN EFFECT: There are no coastal watches or warnings in effect. For storm information specific to your area, please monitor products issued by your national meteorological service. DISCUSSION AND OUTLOOK ---------------------- At 300 AM CST (0900 UTC), the center of Tropical Depression Iota was located near latitude 13.7 North, longitude 88.3 West. Iota is moving toward the west-southwest near 13 mph (20 km/h), and this general motion is expected to continue through today. On the forecast track, the center of Iota will move across El Salvador before the system dissipates later today. Maximum sustained winds have decreased to near 35 mph (55 km/h) with higher gusts. Additional weakening is forecast, and Iota is expected to degenerate into a post-tropical remnant low pressure system later today. The estimated minimum central pressure based on nearby surface observations is 1007 mb (29.74 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Iota can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT1, WMO header WTNT41 KNHC and on the web at www.hurricanes.gov/text/MIATCDAT1.shtml. RAINFALL: Iota is expected to produce the following additional rainfall accumulations through Thursday: Portions of Honduras, Guatemala, southern Belize: 4 to 8 inches (100 to 200 mm), with isolated maximum totals of 12 inches (300 mm). Portions of Nicaragua and El Salvador: 2 to 4 inches (50 to 100 mm), with isolated maximum totals of 6 inches (150 mm). This rainfall will lead to significant, life-threatening flash flooding and river flooding, along with mudslides in areas of higher terrain. 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. Please consult products from your local weather office. NEXT ADVISORY ------------- Next intermediate advisory at 600 AM CST. Next complete advisory at 900 AM CST. $$ Forecaster Stewart

Tropical Depression Twenty-one-E Forecast Discussion Number 3
2020-11-18 09:36:41| National Hurricane Center (East Pacific)
Issued at 100 AM PST Wed Nov 18 2020 000 WTPZ41 KNHC 180836 TCDEP1 Tropical Depression Twenty-One-E Discussion Number 3 NWS National Hurricane Center Miami FL EP212020 100 AM PST Wed Nov 18 2020 The curved band feature that was prominent in earlier satellite images has dissipated, likely due to very dry air surrounding the cyclone. The depression now consists of a small central dense overcast (CDO) that has just recently become established in the past few hours. Earlier ASCAT data indicated that the strongest winds were occurring to the west of the center of the depression, near the curved band that existed at that time, while winds of 20-25 kt were occurring around the center. The nearest sampling by a scatterometer tonight was by the ASCAT-A, which did pass over some of the same area that had the strongest winds earlier, with peak winds now only 20 kt. Assuming the reorganizing of the convection near the center has helped to increased the winds somewhat there, the initial intensity is being held at 30 kt. If the current CDO feature persists this morning, then the depression will likely strengthen to a tropical storm later today. By early Thursday, moderate west-southwesterly shear, cooler oceanic temperatures, and the presence of a very dry and stable air mass should cause the cyclone to begin weakening, and by Thursday night the system is expected to degenerate to a remnant low. The latest NHC intensity forecast is unchanged from the previous one and is in agreement with the various multimodel consensus aids. The initial motion continues to be west-northwestward at 10 kt. The depression is moving to the south of a mid-level ridge, and the cyclone is expected to continue in this general motion through tonight. A turn to the west within the low-level easterly trade wind flow is expected on Thursday as the system loses its deep convection and becomes shallow. The track forecast was nudged a little to the left of the previous advisory track due to a shift in the model guidance in that direction.
