Hurricane Eta Public Advisory Number 45
2020-11-11 15:49:30| National Hurricane Center (Atlantic)
Issued at 1000 AM EST Wed Nov 11 2020 000 WTNT34 KNHC 111449 TCPAT4 BULLETIN Hurricane Eta Advisory Number 45 NWS National Hurricane Center Miami FL AL292020 1000 AM EST Wed Nov 11 2020 ...HEAVY SQUALLS WITH TROPICAL-STORM-FORCE WINDS SPREADING ONSHORE THE SOUTHWESTERN COAST OF FLORIDA... ...STORM SURGE WARNING ISSUED FOR A PORTION OF THE FLORIDA WEST COAST... SUMMARY OF 1000 AM EST...1500 UTC...INFORMATION ----------------------------------------------- LOCATION...26.2N 83.7W ABOUT 115 MI...180 KM WSW OF PORT CHARLOTTE FLORIDA ABOUT 145 MI...235 KM SSW OF TAMPA FLORIDA MAXIMUM SUSTAINED WINDS...75 MPH...120 KM/H PRESENT MOVEMENT...NNE OR 15 DEGREES AT 10 MPH...17 KM/H MINIMUM CENTRAL PRESSURE...983 MB...29.03 INCHES WATCHES AND WARNINGS -------------------- CHANGES WITH THIS ADVISORY: A Storm Surge Warning has been issued for the Florida west coast from Suwannee River to Bonita Beach, including Tampa Bay and Charlotte Harbor. The government of Cuba has discontinued the Tropical Storm Watch for Cuba. SUMMARY OF WATCHES AND WARNINGS IN EFFECT: A Storm Surge Warning is in effect for... * Bonita Beach to Suwanee River Florida, including Tampa Bay and Charlotte Harbor A Hurricane Watch is in effect for... * Anna Maria Island to Yankeetown A Tropical Storm Warning is in effect for... * Dry Tortugas * Bonita Beach to Suwannee River Florida A Storm Surge Watch is in effect for... * Steinhatchee River to Suwannee River Florida A Tropical Storm Watch is in effect for... * North of the Suwannee River to Aucilla River Florida A Hurricane Watch means that hurricane conditions are possible within the watch area, in this case within 24 hours. A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area, in this case within 24 hours. A Storm Surge Warning means there is a danger of life-threatening inundation, from rising water moving inland from the coastline, in this case within 24 hours in the indicated locations. For a depiction of areas at risk, please see the National Weather Service Storm Surge Watch/Warning Graphic, available at hurricanes.gov. This is a life-threatening situation. Persons located within these areas should take all necessary actions to protect life and property from rising water and the potential for other dangerous conditions. Promptly follow evacuation and other instructions from local officials. A Storm Surge Watch means there is a possibility of life- threatening inundation, from rising water moving inland from the coastline, in this case within 24 hours. For a depiction of areas at risk, please see the National Weather Service Storm Surge Watch/Warning Graphic, available at hurricanes.gov. A Tropical Storm Watch means that tropical storm conditions are possible within the watch area. Interests elsewhere along the Gulf Coast of Florida should monitor the progress of Eta. Additional warnings may be required along portions of the Florida Peninsula today. 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 Hurricane Eta was located near latitude 26.2 North, longitude 83.7 West. Eta is moving toward the north-northeast near 10 mph (17 km/h), and this general motion is expected to continue through Thursday. On the forecast track, the center of Eta will move closer to but offshore of the southwest coast of Florida today, approach the west-central coast of Florida tonight, and move inland over the northern portion of the Florida peninsula on Thursday. Eta is expected to move northeastward into the western Atlantic late Thursday or early Friday. Data from NOAA Doppler weather radars indicate that maximum sustained winds remain near 75 mph (120 km/h) with higher gusts. Eta could be near hurricane strength tonight as it approaches the west coast of Florida, with rapid weakening expected after landfall on Thursday. Hurricane-force winds extend outward up to 60 miles (95 km), mainly northeast of the center, and tropical-storm-force winds extend outward up to 115 miles (185 km). A sustained wind of 33 mph (53 km/h) and a gust to 42 mph (68 km/h) were recently measured by a Weatherflow observing station on Sanibel Island. Across the lower Florida Keys, a sustained wind of 39 mph (63 km/h) and a gust to 49 mph (91 km/h) were recently reported at Sand Key. The estimated minimum central pressure is 983 mb (29.03 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. STORM SURGE: The combination of a dangerous storm surge and the tide will cause normally dry areas near the coast to be flooded by rising waters moving inland from the shoreline. The water could reach the following heights above ground somewhere in the indicated areas if the peak surge occurs at the time of high tide... Anclote River to Boca Grande, FL including Tampa Bay...3-5 ft Boca Grande, FL to Bonita Beach, FL including Charlotte Harbor...2-4 ft Steinhatchee River to Anclote River...2-4 ft Bonita Beach to Flamingo...1-2 ft The deepest water will occur along the immediate coast in areas of onshore flow, where the surge will be accompanied by large and dangerous waves. Surge-related flooding depends on the relative timing of the surge and the tidal cycle, and can vary greatly over short distances. For information specific to your area, please see products issued by your local National Weather Service forecast office. RAINFALL: Eta is expected to produce the following rainfall totals: Western Cuba: an additional 1 to 3 inches (25 to 75 mm) today, with isolated maximum storm total accumulations of 25 inches (765 mm). West and central Florida: through Friday, 2 to 4 inches, with maximum storm total accumulations of 6 inches. North and South Florida: an additional 1 to 2 inches, with isolated maximum storm total accumulations of 4 inches in North Florida and 20 inches in South Florida. Flash and river flooding will be possible in western Cuba on Wednesday, along with landslides in areas of higher terrain. Additional flash and urban flooding will be possible in South Florida, especially across previously inundated areas. Flash,urban, and isolated minor river flooding is expected across portions of West and North Florida through Friday. WIND: Hurricane conditions are possible in the watch area tonight and early Thursday. Tropical storm conditions are expected in the Dry Tortugas through early afternoon. Tropical storm conditions are expected in the Tropical Storm Warning area along the Florida west coast by this afternoon. Tropical Storm conditions are possible in the watch area along the Florida Big Bend region by Thursday. TORNADOES: A few tornadoes are possible through tonight over parts of western and central Florida. SURF: Swells generated by Eta are expected to affect the north coast of Cuba, southern and western Florida, and the Florida Keys during the next day or so. 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 Stewart
