In coastal Georgia, Ian’s winds were already beginning to topple trees and power lines on Thursday afternoon, with 8,000 customers without power at 3 p.m. EDT on Thursday, September 29, Ian had knocked out power to over 2.6 million customers in Florida – approximately 24% of the state’s customers – according to. Ian knocks out power to over 2.6 million in FloridaĪs of 3 p.m. These numbers alone suggest that the damages from Ian will likely far exceed the impacts from Donna. The population of Lee County (which comprises the Cape Coral-Fort Myers metro area) has skyrocketed from 54,000 in 1960 to more than 750,000 today, and the population of Collier County (which comprises the Naples-Immokalee-Marco Island metro area) has soared from 15,000 in 1960 to more than 380,000 today. One big change is that the area had far fewer residents when Donna struck in 1960. There were multiple reports of inundations from Donna of 8 to 12 feet in the Naples area and 7 to 11 feet in the Fort Myers area. Wednesday, it recorded a peak water level above MHHW of 6.18 feet, far above the record since 1965 of 4.02 feet set in Hurricane Irma (September 10, 2017).Īpart from these gauge reports, the highest inundations on Wednesday from Fort Myers to Naples in some areas were likely as high as, or higher than, than those observed in Hurricane Donna in 1960, before complete records were kept. Before the tide gauge at Naples went out of service during the storm around 1 p.m. The storm surge at the Fort Myers tide gauge brought a water level that peaked at 7.25 feet Wednesday, smashing the previous record of 3.41 feet above mean higher high water (MHHW) set in Tropical Storm Keith (November 23, 1988). Here’s what’s left of Times Square in Fort Myers Beach /dw9OXzbtAz- Vikeologist™ September 29, 2022 A CoCoRaHS site near New Smyrna Beach recorded an astounding 28.60 inches of rain in 27 hours. Thirteen river gauges were at major flood stage on Thursday afternoon, and four rivers or creeks were at their highest flood stages on record. The National Weather Service office in Melbourne, Florida, issued flash flood emergency warnings for three separate areas in east-central Florida on Thursday morning, including Daytona Beach and Sanford. Rainfall records extend back to 1892 at Orlando. This rainfall crushes Orlando’s previous 24-hour record of 9.67 inches set on Sept. EDT Thursday, causing heavy flooding near Kissimmee. Orlando logged 12.49 inches of rain in the 24 hours ending at 8 a.m. (Image credit: Sam Lillo, h/t to Kathryn Prociv) Ian was moving at about 9 mph, which is about 30% slower than average. Along Ian’s track over Florida, the average forward speed was approximately 11 knots (13 mph). Average forward speed in for Atlantic tropical cyclones knots (multiply by 1.15 to convert to mph). These two factors – higher sea surface temperatures and a slowdown in post-landfall movement of Atlantic storms in the United States – are among the multiple ways in which human-warmed atmosphere has been linked to hurricane behavior. Unusually warm waters near 29 degrees Celsius along Florida’s east coast – one degree Celsius (1.8☏) above average – contributed to the record rains. At 5 a.m., Ian passed about 40 miles southeast of Orlando, by then weakened to a tropical storm with 65 mph winds.ĭry air on the south side of Ian’s circulation limited the amount of rain that fell to the right side of its track, but the hurricane’s intensity, large size, and relatively slow forward speed (30% slower than average) allowed it to dump prodigious amounts of rain along the left side of the track. Thursday, when it was about 100 miles inland from its initial landfall point. Ian maintained hurricane strength until 2 a.m. EDT Wednesday, Ian gradually weakened as it moved across Florida at 8 – 9 mph.
