SUMMARY OF WATCHES AND WARNINGS IN EFFECT: A Tropical Storm Warning is in effect for... * Bermuda A Tropical Storm Warning means that tropical storm conditions are expected within the warning area, in this case during the next several hours. For storm information specific to your area, please monitor products issued by your national meteorological service. DISCUSSION AND OUTLOOK ---------------------- At 1100 PM AST (0300 UTC), the center of Hurricane Humberto was located near latitude 34.0 North, longitude 63.9 West. Humberto is moving toward the northeast near 23 mph (37 km/h). This general motion is expected to continue through Thursday, followed by a north-northeastward motion at a slower forward speed Thursday night and Friday. A turn toward the east-northeast is expected Friday night and Saturday. On the forecast track, the center of Humberto will continue to move away from Bermuda tonight. Reports from an Air Force Reserve Hurricane Hunter aircraft indicate that maximum sustained winds remain near 120 mph (195 km/h) with higher gusts. Humberto is a category 3 hurricane on the Saffir-Simpson Hurricane Wind Scale. The hurricane should start to weaken later tonight, and it is expected to become a post-tropical cyclone by Friday. Hurricane-force winds extend outward up to 90 miles (150 km) from the center and tropical-storm-force winds extend outward up to 220 miles (350 km). Several stations on Bermuda are reporting sustained winds of 40-50 mph (65-80 km/h) with higher gusts. The minimum central pressure reported by the Hurricane Hunter aircraft is 952 mb (28.12 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Humberto can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT4 and WMO header WTNT44 KNHC and on the web at www.hurricanes.gov/text/MIATCDAT4.shtml. WIND: Tropical-storm-force winds will persist on Bermuda into late Thursday morning. RAINFALL: Humberto may bring periods of heavy rain to Bermuda through Thursday, with rainfall accumulations of 2 to 4 inches with maximum amounts of 6 inches expected. SURF: Large swells and dangerous surf generated by Humberto will continue along the coast of Bermuda through Thursday, and these could cause coastal flooding. Swells will continue to affect the northwestern Bahamas and the southeastern coast of the United States from east-central Florida to North Carolina during the next couple of days. These swells could cause life-threatening surf and rip current conditions. Please consult products from your local weather office and the Bermuda Weather Service. STORM SURGE: Storm surge along the coast of Bermuda should subside tonight and Thursday. NEXT ADVISORY ------------- Next intermediate advisory at 200 AM AST. Next complete advisory at 500 AM AST. $$ Forecaster Beven

Tropical Storm Jerry Forecast Discussion Number 7

5 years 8 months ago
Issued at 1100 PM AST Wed Sep 18 2019 000 WTNT45 KNHC 190240 TCDAT5 Tropical Storm Jerry Discussion Number 7 NWS National Hurricane Center Miami FL AL102019 1100 PM AST Wed Sep 18 2019 Jerry is gradually becoming better organized, with a small circular CDO and some banding features over its northwestern quadrant. Although the storm has some modest upper-level outflow, there is evidence of west-northwesterly winds undercutting the system just below the outflow layer. An upper-level cyclone is located a few hundred miles to the northwest of Jerry, as confirmed by synoptic surveillance observations taken recently by the NOAA G-IV jet. However, the global models suggest that this feature should remain far enough to the north of the tropical cyclone so that its shearing influence will be minimal in the short term. The current intensity estimate is 55 kt based on Dvorak classifications from TAFB and SAB. Since the environment is likely to be modestly conducive during the next day or so, strengthening is predicted for the next 24 hours. Thereafter, the dynamical guidance shows some increase in shear, which should result in a leveling off of Jerry's intensity. Later in the forecast period, the global models predict a significant increase in shear, so some weakening is likely. The official intensity forecast is close to the multi-model consensus. The storm remains on track with the motion continuing around 290/13 kt. There are no important changes to the track forecast from the previous advisory. Jerry should move along the southwestern periphery of a subtropical ridge over the next couple of days. In 3-5 days, the tropical cyclone is likely to turn northwest, north-northwest, and eventually north following a weakness in the ridge near 70-75W longitude. The official track forecast is close to the latest corrected multi-model consensus guidance. Key Messages: 1. Jerry is expected to become a hurricane before it moves close to the northern Leeward Islands Friday. Although the core of Jerry is currently expected to pass north of the islands, tropical-storm- force winds and locally heavy rainfall are possible, and tropical storm watches have been issued for a portion of this area.
