TO: All Hospital Emergency Management Contacts FROM: John Wilgis, Vice President of Member and Corporate Services SUBJECT: Hurricane Ida Afternoon Update DATE: August 27, 2021 New information in red. Location: 20.3N 81.7W Maximum Sustained Winds: 60 miles per hour Present Movement: Northwest at 15 miles per hour Minimum Central Pressure: 996 millibars (29.41 Inches) Forecast Track Watches and Warnings A Tropical Storm Watch is in effect for Mississippi/Alabama border to the Alabama/Florida border. A Tropical Storm Watch means that tropical storm conditions are possible within the watch area, generally within 48 hours. A Storm Surge Watch is in effect for Sabine Pass to Alabama / Florida border. A Storm Surge Watch means there is a possibility of life-threatening inundation, from rising water moving inland from the coastline, in the indicated locations during the next 48 hours. Discussion At 2:00 p.m., ET, the center of Hurricane Ida was located by Cuban radar and Air Force Reserve Hurricane Hunter aircraft near latitude 21.6 north, longitude 82.7 west. Ida is moving toward the northwest near 15 miles per hour and this general motion should continue over the next few days. On the forecast track, the center of Ida will pass over the Isle of Youth during the next hour or so, move over western Cuba later today, and move over the southeastern and central Gulf of Mexico tonight and Saturday. Ida is forecast to make landfall along the U.S. northern Gulf Coast within the hurricane watch area on Sunday. Reports from Air Force Reserve reconnaissance aircraft indicate that the maximum sustained winds are near 75 miles per hour with higher gusts. Additional strengthening is forecast before the center moves over western Cuba later today. Steady to rapid strengthening is expected when Ida moves over the southeastern and central Gulf of Mexico over the weekend, and Ida is expected to be a major hurricane when it approaches the northern Gulf coast. Hurricane-force winds extend outward up to 20 miles from the center. Tropical-storm-force winds extend outward up to 90 miles from the center. Sustained winds of 38 miles per hour and a gust to 55 miles per hour has recently been observed on Cayo Largo, Cuba. The latest minimum central pressure estimated from Air Force Reserve reconnaissance aircraft data is 987 millibars (29.15 inches). Supply Line Interruptions Expected Hurricane Ida is forecast to be a major storm impacting the southeast Gulf Coast on Sunday and Monday. The Florida Division of Emergency Management is asking hospitals to consider the impacts to their supply lines that traverse the Interstate 10 (I-10) corridor through Louisiana, Mississippi, Alabama, and Florida over the next several days. There will likely be road closures and traffic delays and hospitals should consider the impact to their ability to obtain material resources. FHA will be monitoring Ida through the weekend and providing necessary updates. In an effort to better coordinate the hospital and health system resource request from County, State and Federal caches for COVID-19, the Florida Division of Emergency Management and Florida Department of Health (State ESF-8 Health and Medical Services) have created a flow diagram outlining the proper process to request resources. Hospitals and health systems are asked to follow this process. Any requests made through other channels will not be accepted and only delay delivery of needs supplies and equipment Please contact John Wilgis at (850) 524-2037 for more information. Hazards Affecting Land Stormsurge: 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: MS/AL border to AL/FL border including Mobile Bay - 3-5 feet Overtopping of local levees outside of the Hurricane and Storm Damage Risk Reduction System is possible where local inundation values may be higher than those shown above. The deepest water will occur along the immediate coast near and to the east of the landfall location, 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. Wind: Hurricane conditions are possible in the hurricane watch area along the northern Gulf coast late Saturday night or Sunday and tropical storm conditions are possible in the watch area late Saturday night or Sunday. Rainfall: As Ida approaches the central Gulf Coast Sunday afternoon, total rainfall accumulations of 8 to 16 inches with isolated maximum amounts of 20 inches are possible from southeast Louisiana to coastal Mississippi and Alabama through Monday morning. Ida is forecast to turn northeast as it moves inland later Monday with rainfall totals of 4 to 8 inches possible across southern and central Mississippi. This is likely to result in considerable flash, urban, small stream, and riverine flooding. Surf: Swells will begin reaching portions of the northern Gulf coast Saturday night or early Sunday. These swells are likely to cause life-threatening surf and rip current conditions. More information is available from the National Hurricane Center. Please monitor conditions from your local weather service for potential impacts to your community.
