Tropical Storm Eta Public Advisory Number 49
2020-11-12 15:46:48| National Hurricane Center (Atlantic)
Issued at 1000 AM EST Thu Nov 12 2020 000 WTNT34 KNHC 121446 TCPAT4 BULLETIN Tropical Storm Eta Advisory Number 49 NWS National Hurricane Center Miami FL AL292020 1000 AM EST Thu Nov 12 2020 ...CENTER OF ETA MOVING OVER NORTHEASTERN FLORIDA... ...STILL PRODUCING LOCALLY HEAVY RAINS AND GUSTY WINDS OVER PORTIONS NORTHEASTERN FLORIDA AND FAR SOUTHEASTERN GEORGIA... SUMMARY OF 1000 AM EST...1500 UTC...INFORMATION ----------------------------------------------- LOCATION...30.2N 81.8W ABOUT 10 MI...15 KM SW OF JACKSONVILLE FLORIDA MAXIMUM SUSTAINED WINDS...45 MPH...75 KM/H PRESENT MOVEMENT...NNE OR 30 DEGREES AT 15 MPH...24 KM/H MINIMUM CENTRAL PRESSURE...1003 MB...29.62 INCHES WATCHES AND WARNINGS -------------------- CHANGES WITH THIS ADVISORY: None SUMMARY OF WATCHES AND WARNINGS IN EFFECT: A Tropical Storm Warning is in effect for... * Flagler/Volusia County Florida line northward to St. Andrews Sound Georgia. A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area. For storm information specific to your area, including possible inland watches and warnings, please monitor products issued by your local National Weather Service forecast office. DISCUSSION AND OUTLOOK ---------------------- At 1000 AM EST (1500 UTC), the center of Tropical Storm Eta was located near latitude 30.2 North, longitude 81.8 West. Eta is moving toward the north-northeast near 15 mph (24 km/h). A faster northeastward motion is expected over the next couple of days. On the forecast track, the center of Eta will emerge into the western Atlantic by early this afternoon. The cyclone is expected to accelerate over the western Atlantic and move parallel to, but offshore of the Carolinas tonight and early Friday before heading well east of the Mid-Atlantic coast by late Friday. Maximum sustained winds are near 45 mph (75 km/h) with higher gusts. Little change in strength is forecast through early Friday. Eta could re-intensify as a non-tropical cyclone late Friday or Friday night before becoming absorbed by a larger non-tropical cyclone on Saturday. Tropical-storm-force winds extend outward up to 115 miles (185 km) primarily over water to the east of the center. A NOAA Coastal Marine Observing site at St. Augustine Florida reported sustained winds of 39 mph (63 km/h) and a gust of 44 mph (70 km/h). A wind gust to 43 mph (69 km/h) was recently reported at the Mayport Naval Air Station near Jacksonville, Florida. The estimated minimum central pressure is 1003 mb (29.62 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Eta can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT4, WMO header WTNT44 KNHC, and on the web at www.hurricanes.gov/text/MIATCDAT4.shtml. RAINFALL: Eta will produce an additional 1 to 3 inches of rain across portions of the Florida Peninsula through today, with isolated maximum storm total accumulations of 20 to 25 inches in South Florida. Localized flash and urban flooding will be possible across the Florida Peninsula today, especially across previously inundated areas. Minor river flooding is expected across portions of West Florida lasting into the weekend. WIND: Tropical storm conditions are expected in the Tropical Storm Warning area along the east coast of Florida through early this afternoon. SURF: Swells generated by Eta are expected to affect the Florida Gulf Coast today, and begin to affect portions of the coast of the southeastern United States later today. 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 100 PM EST. Next complete advisory at 400 PM EST. $$ Forecaster Brown

Tropical Storm Theta Forecast Discussion Number 11

Issued at 300 PM GMT Thu Nov 12 2020 000 WTNT45 KNHC 121445 TCDAT5 Tropical Storm Theta Discussion Number 11 NWS National Hurricane Center Miami FL AL302020 300 PM GMT Thu Nov 12 2020 Although the cloud top temperatures across the broad comma-shaped convective shield have warmed this morning, there is some new convection that has been developing nearer to Theta's center over the past few hours. Unfortunately, the scatterometer passes this morning missed sampling the winds near the center of the cyclone. However, the partial ASCAT-A overpass showed that 45 kt winds are occurring nearly 100 n mi to the southwest of the center of Theta. Therefore it is assumed that stronger winds are still occurring closer to the center of the cyclone, and the initial intensity is being held at 55 kt. Theta has now turned to the right, and the initial motion is 080/10 kt. For about the next 36 h, the cyclone is expected to continue moving just north of east around the north side of a mid-level ridge. A slower east-southeastward motion is expected from 36-72 h as the mid-level ridge to the south weakens and mid- to upper-level northerly flow moves over Theta. After 72 h, Theta or its remnants are expected to turn northeastward or northward and accelerate in the low-level flow ahead of an approaching deep-layer mid-latitude cyclone over the northeastern Atlantic. The latest track forecast is little changed from the previous one and is near the multi-model consensus tracks. The shear across Theta is expected to relax somewhat over the day or so, while moving over cooler waters. The counteracting effects should allow the cyclone to maintain its intensity. By this weekend, strong northerly shear is expected to impact Theta, while stable air gets entrained into its circulation. This should cause the cyclone to weaken, with the system likely degenerating into a remnant low by Sunday. The latest NHC intensity forecast is just slightly above the guidance through 60 h, and is near the various consensus models thereafter.
