Hurricane Epsilon Public Advisory Number 9A
2020-10-21 13:43:02| National Hurricane Center (Atlantic)
Issued at 800 AM AST Wed Oct 21 2020 000 WTNT32 KNHC 211142 TCPAT2 BULLETIN Hurricane Epsilon Intermediate Advisory Number 9A NWS National Hurricane Center Miami FL AL272020 800 AM AST Wed Oct 21 2020 ...EPSILON COULD STRENGTHEN A LITTLE MORE TODAY... SUMMARY OF 800 AM AST...1200 UTC...INFORMATION ---------------------------------------------- LOCATION...28.9N 58.8W ABOUT 425 MI...685 KM ESE OF BERMUDA MAXIMUM SUSTAINED WINDS...85 MPH...140 KM/H PRESENT MOVEMENT...WNW OR 285 DEGREES AT 14 MPH...22 KM/H MINIMUM CENTRAL PRESSURE...976 MB...28.82 INCHES WATCHES AND WARNINGS -------------------- CHANGES WITH THIS ADVISORY: None SUMMARY OF WATCHES AND WARNINGS IN EFFECT: A Tropical Storm Watch is in effect for... * Bermuda A Tropical Storm Watch means that tropical storm conditions are possible within the watch area, in this case within 36 hours. For storm information specific to your area, please monitor products issued by your national meteorological service. DISCUSSION AND OUTLOOK ---------------------- At 800 AM AST (1200 UTC), the eye of Hurricane Epsilon was located by satellite images near latitude 28.9 North, longitude 58.8 West. Epsilon has taken a westward jog this morning but is generally moving toward the west-northwest near 14 mph (22 km/h). A west-northwestward motion at a slower forward speed is expected today. A turn toward the northwest is expected tonight, followed by a turn toward the north by Thursday night. On the forecast track, the center of Epsilon is forecast to make its closest approach to Bermuda Thursday afternoon or evening. Maximum sustained winds are near 85 mph (140 km/h) with higher gusts. Some additional strengthening is possible today, followed by little change in strength into the weekend. Hurricane-force winds extend outward up to 25 miles (35 km) from the center and tropical-storm-force winds extend outward up to 435 miles (705 km) mainly to the north of the center. The estimated minimum central pressure is 976 mb (28.82 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Tropical storm conditions are possible on Bermuda on Thursday. SURF: Large swells generated by Epsilon are affecting Bermuda, the Bahamas, the Greater Antilles, and the Leeward Islands, and are expected to reach portions of the east coast of the United States and Atlantic Canada during the next couple of days. 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 1100 AM AST. $$ Forecaster Reinhart/Blake

Hurricane Epsilon Forecast Discussion Number 9
2020-10-21 10:52:59| National Hurricane Center (Atlantic)
Issued at 500 AM AST Wed Oct 21 2020 935 WTNT42 KNHC 210852 TCDAT2 Hurricane Epsilon Discussion Number 9 NWS National Hurricane Center Miami FL AL272020 500 AM AST Wed Oct 21 2020 Epsilon has maintained an eye in infrared satellite images during the past few hours, although a 0522 UTC AMSR microwave image indicated that the eastern and southern eyewall were a little thin at the time. Still, Dvorak estimates from TAFB and SAB, and the UW-CIMSS ADT, unanimously increased to T4.5/77 kt, and Epsilon's intensity is therefore set at 75 kt. By definition, Epsilon has rapidly intensified, its intensity increasing more than 30 kt during the past 24 hours. As expected, Epsilon has turned toward the west-northwest with an initial motion of 300/12 kt, in response to a mid-tropospheric ridge which has built to the north of the hurricane. This ridge is expected to cede control to another ridge positioning itself east of Epsilon during the next 24 hours, which should steer the cyclone back to the northwest and then north Thursday and Thursday night. Epsilon is then expected to become embedded in the mid-latitude westerlies this weekend, accelerating northeastward toward the north Atlantic by the end of the forecast period. The GFS and HWRF models are showing some deviation to the east and west, respectively, of the other tightly packed guidance during the expected recurvature to the east of Bermuda. However, given that that there is little spread among the other models, the NHC track prediction remains close to the simple and corrected multi-model consensus aids. Relatively low vertical shear could foster some additional strengthening today, but oceanic heat content values are expected to fall to zero in 12-24 hours, which is likely to temper how much intensification can occur. During the first few days, the NHC intensity forecast lies between the nearly steady-state HCCA and IVCN aids and the slightly higher SHIPS and LGEM models. This forecast allows for some modest strengthening but generally shows little change in strength for the next 3 days. Some gradual weakening is anticipated on days 4 and 5 as Epsilon merges with a cold front and becomes extratropical, but it is likely to still be a powerful cyclone as it moves toward the north Atlantic at the end of the forecast period. Key Messages: 1. Tropical storm conditions are possible on Bermuda on Thursday, when Epsilon is forecast to make its closest approach east of the island as a hurricane. 2. Dangerous surf and rip currents are likely occurring along the coasts of Bermuda, the Bahamas, the Greater Antilles, and the Leeward Islands. These conditions are expected to spread to portions of the east coast of the United States and Atlantic Canada during the next couple of days.
