Hurricane Epsilon Public Advisory Number 13A
2020-10-22 07:49:45| National Hurricane Center (Atlantic)
Issued at 200 AM AST Thu Oct 22 2020 000 WTNT32 KNHC 220549 TCPAT2 BULLETIN Hurricane Epsilon Intermediate Advisory Number 13A NWS National Hurricane Center Miami FL AL272020 200 AM AST Thu Oct 22 2020 ...EPSILON MAKES A WOBBLY TURN TOWARD THE NORTHWEST... SUMMARY OF 200 AM AST...0600 UTC...INFORMATION ---------------------------------------------- LOCATION...30.3N 60.5W ABOUT 285 MI...460 KM ESE OF BERMUDA MAXIMUM SUSTAINED WINDS...115 MPH...185 KM/H PRESENT MOVEMENT...NW OR 320 DEGREES AT 7 MPH...11 KM/H MINIMUM CENTRAL PRESSURE...953 MB...28.15 INCHES WATCHES AND WARNINGS -------------------- CHANGES WITH THIS ADVISORY: None 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 somewhere within the warning area within 36 hours. For storm information specific to your area, please monitor products issued by your national meteorological service. DISCUSSION AND OUTLOOK ---------------------- At 200 AM AST (0600 UTC), the center of Hurricane Epsilon was located near latitude 30.3 North, longitude 60.5 West. Epsilon has been wobbling during the past few hours, but its longer-term motion is now toward the northwest near 7 mph (11 km/h). This northwestward motion is expected to continue today. The hurricane is forecast to turn toward the north-northwest late today and toward the north on Friday. On the forecast track, the center of Epsilon is forecast to make its closest approach to Bermuda later this evening. Maximum sustained winds are near 115 mph (185 km/h) with higher gusts. Epsilon is a category 3 hurricane on the Saffir-Simpson Hurricane Wind Scale. Small fluctuations in intensity are possible through this morning, but a weakening trend is expected to begin later today and continue 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 345 miles (555 km) mainly to the north of the center. The estimated minimum central pressure is 953 mb (28.15 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Tropical storm conditions are expected intermittently on Bermuda through this evening. 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 500 AM AST. $$ Forecaster Berg

Hurricane Epsilon Forecast Discussion Number 13

Issued at 1100 PM AST Wed Oct 21 2020 000 WTNT42 KNHC 220241 TCDAT2 Hurricane Epsilon Discussion Number 13 NWS National Hurricane Center Miami FL AL272020 1100 PM AST Wed Oct 21 2020 The eye of the hurricane remains well-defined this evening, although the surrounding cloud tops are beginning to warm a bit. An Air Force Hurricane Hunter aircraft investigated Epsilon a little while ago and found peak 700 mb flight level winds of 110 kt, which continues to support an intensity of 100 kt. The central pressure had fallen slightly since this afternoon, but recent center fixes suggest that it is leveling off. Some fluctuations in intensity are possible over the next 12 hours or so due to inner-core processes. Later on Thursday, a slow weakening trend is expected to begin as vertical shear over Epsilon should gradually increase. The official intensity forecast is in good agreement with the latest model consensus. By 96 hours, the global models indicate that the strong cyclone will merge with a frontal zone over the mid-latitudes, and the NHC forecast shows the system as extratropical by that time. Epsilon's motion has exhibited what is likely a trochoidal wobble, which is typical of slow-moving intense hurricanes. This has resulted in a more westward track during the past 6 hours or so. The initial motion estimate is 285/7 kt, and is indeed more westward than previous estimates. However, recent satellite images indicate little short-term motion. The track model guidance is in very good agreement that Epsilon will move northwestward and then north-northwestward on Friday and Friday night. Later, the cyclone should move north of the subtropical ridge, and turn northward and northeastward. By days 4-5, the cyclone should accelerate northeastward under the influence of the mid-latitude westerlies. The official forecast is right on top of the latest corrected multi-model consensus guidance, HCCA and is only slightly west of the previous NHC track through 24 hours. This puts the closest approach of Epsilon to Bermuda between 00Z and 06Z Friday. Key Messages: 1. Tropical storm conditions are expected on Bermuda tonight, and continuing intermittently through late Thursday, when Epsilon is forecast to make its closest approach east of the island. A Tropical Storm Warning is in effect for Bermuda. 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.
