TO: All Hospital Emergency Management Contacts FROM: John Wilgis, Vice President of Member and Corporate Services SUBJECT: Tropical Storm Ida Morning Update - August 27, 2021 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 Estimated Arrival Time for Tropical Storm Force Winds Forecast Rainfall Watches and Warnings 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 8:00 a.m., ET, center of Tropical Storm Ida was located by reconnaissance aircraft and weather radar on Grand Cayman near latitude 20.3 north, longitude 81.7 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 move away from the Cayman Islands this morning, pass near or over the Isle of Youth and western Cuba later today, and move over the southeastern and central Gulf of Mexico tonight and Saturday. The system is forecast to approach the U.S. northern Gulf coast on Sunday. Data from Air Force Reserve and National Oceanic and Atmospheric Administration reconnaissance aircraft indicate that the maximum sustained winds have increased to near 60 miles per hour with higher gusts, and additional steady to rapid strengthening is expected during the next few days. Ida is forecast to become a hurricane over the southeastern Gulf of Mexico, and to be at or near major hurricane strength when it approaches the northern Gulf coast. Tropical-storm-force winds extend outward up to 80 miles. The estimated minimum central pressure from reconnaissance aircraft data is 996 millibars (29.41 inches). Hazards Affecting Land Stormsurge: A dangerous storm surge will raise water levels by as much as 2 to 4 feet above normal tide levels in areas of onshore winds along the immediate coast of the Isle of Youth and near and to the east of where the center crosses the coast of western Cuba. Near the coast, the surge will be accompanied by large and destructive waves. 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. More information is available from the National Hurricane Center. Please monitor conditions from your local weather service for potential impacts to your community.
