Hurricane Epsilon Public Advisory Number 14A
2020-10-22 13:58:18| National Hurricane Center (Atlantic)
Issued at 800 AM AST Thu Oct 22 2020 000 WTNT32 KNHC 221158 TCPAT2 BULLETIN Hurricane Epsilon Intermediate Advisory Number 14A NWS National Hurricane Center Miami FL AL272020 800 AM AST Thu Oct 22 2020 ...AIR FORCE RESERVE HURRICANE HUNTERS FIND THAT EPSILON HAS DROPPED IN INTENSITY... ...TROPICAL STORM CONDITIONS STILL EXPECTED ON BERMUDA TODAY... SUMMARY OF 800 AM AST...1200 UTC...INFORMATION ---------------------------------------------- LOCATION...30.6N 61.3W ABOUT 235 MI...385 KM ESE OF BERMUDA MAXIMUM SUSTAINED WINDS...100 MPH...155 KM/H PRESENT MOVEMENT...NW OR 305 DEGREES AT 7 MPH...11 KM/H MINIMUM CENTRAL PRESSURE...962 MB...28.41 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. 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 an Air Force Reserve Hurricane Hunter aircraft near latitude 30.6 North, longitude 61.3 West. Epsilon has been wobbling toward the west recently, but its longer-term motion is toward the northwest near 7 mph (11 km/h). A turn toward the north-northwest is expected later today, followed by a northward motion tonight through Friday night, and an acceleration toward the northeast on Saturday. On the forecast track, the center of Epsilon is forecast to make its closest approach to, but well to the east of, Bermuda later this evening. Maximum sustained winds have decreased to near 100 mph (155 km/h) with higher gusts. Slow weakening is forecast during the next few days. Hurricane-force winds extend outward up to 25 miles (35 km) from the center and tropical-storm-force winds extend outward up to 310 miles (500 km). The estimated minimum central pressure is 962 mb (28.41 inches) based on Air Force Reserve dropsonde data. HAZARDS AFFECTING LAND ---------------------- WIND: Tropical storm conditions are expected intermittently on Bermuda through this evening. SURF: Large swells generated by Epsilon will affect Bermuda, the Bahamas, the Greater Antilles, the Leeward Islands, the east coast of the United States, and Atlantic Canada during the next few 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 Blake/Papin

Hurricane Epsilon Forecast Discussion Number 14
2020-10-22 10:48:44| National Hurricane Center (Atlantic)
Issued at 500 AM AST Thu Oct 22 2020 000 WTNT42 KNHC 220848 TCDAT2 Hurricane Epsilon Discussion Number 14 NWS National Hurricane Center Miami FL AL272020 500 AM AST Thu Oct 22 2020 Epsilon's eye has lost some definition and become cloud filled in conventional satellite imagery during the past few hours, and an 0604 UTC AMSR2 microwave image showed that the eyewall has been eroded on the west side. Given the degradation of the cloud pattern and lowering Dvorak estimates, Epsilon's initial intensity is being set, likely generously, at 95 kt. A recent UW-CIMSS SATCON estimate suggests that the intensity could be 10-15 kt lower than that, but I'd rather we see the aircraft reconnaissance data in a few hours before reducing it any further. Epsilon's trochoidal wobbles have continued overnight, but a longer-term 12-hour motion suggests that the hurricane has turned toward the northwest (320/6 kt). A mid-tropospheric high over the central Atlantic will be Epsilon's main driver, causing the hurricane to turn toward the north-northwest later today and then toward the north tonight. Shorter-term deviations around this general trajectory will be possible if the trochoidal oscillations continue through the day. Epsilon is forecast to turn toward the northeast and accelerate on Saturday when it becomes embedded in the mid-latitude westerlies, taking it past southeastern Newfoundland and into the north Atlantic early next week. The new NHC track forecast is down the middle of the tightly clustered model guidance, and close to the TVCN multi-model consensus. However, because of the recent wobbles, this new forecast lies about 40 n mi to the east of the previous forecast during the first 36 hours. Epsilon's forecast track takes it over a rather homogeneous field of sea surface temperatures between 25-26 degrees Celsius for the next 48-60 hours as vertical shear increases somewhat. Gradual weakening is anticipated during that period, but a more sudden decrease in ocean temperatures after 60 hours should induce quicker weakening thereafter. Hurricane and global models both agree on this scenario, and the NHC intensity forecast is very close to the IVCN consensus and the HFIP Corrected Consensus. Epsilon is expected to merge with a frontal zone and become extratropical by day 4. Key Messages: 1. Tropical storm conditions are expected intermittently on Bermuda through this evening, when Epsilon is forecast to make its closest approach east of the island. A Tropical Storm Warning is in effect for Bermuda. 2. Dangerous and potentially life-threatening surf and rip currents are expected along the coasts of Bermuda, the Bahamas, the Greater Antilles, the Leeward Islands, the east coast of the United States, and Atlantic Canada during the next couple of days.
