1960: Hurricane Donna slammed into the Florida Keys in 1960 with wind speeds of 200 mph. The Atlantic hurricane season officially began on June 15, 1964. It was a slightly above average season in which twelve tropical storms formed, compared with the 1950–2000 average of 9.6 named storms. Project Stormfury was an attempt to weaken tropical cyclones by flying aircraft into them and seeding with silver iodide.The project was run by the United States Government from 1962 to 1983. All six of the hurricanes reached major hurricane … Author Jay Barnes in North Carolina's Hurricane History also reports wind gusts of 122 mph on Figure Eight Island and 105 mph in New Bern. One report from an offshore oilrig indicates wind speeds … It then struck southwest Florida, taking a northeasterly path as it crossed the state until it … The resulting scaling model for the effective fetch and duration should therefore be applied with the flight-level wind speed. Though officially the top wind speed is 233 km/h (145 mph), other unofficial reports exist. She's talking about Hurricane Donna - which made landfall on the same day as Irma 57 years ago. The 1935 Labor Day hurricane (formally known as Hurricane Three) was the most intense Atlantic hurricane to make landfall on record in terms of both pressure and wind speed. Wind gusts were measured at 100 mph in Greenville, 81 mph in Goldsboro, and 79 mph in both Fayetteville and Raleigh. It remains the only storm to bring hurricane force winds to Florida, the Mid-Atlantic and … Hurricane Donna … The U.S. state of Florida received the most damage from Hurricane Donna. Portions of southern and western Florida received over 10 in (250 mm) of rainfall from the hurricane, peaking at 13.24 in (336 mm). Six of these reached hurricane status, which is near the 1950–2000 average of 5.9. Strong winds were observed in the state, with a sustained wind speed … The Saffir-Simpson Hurricane Wind Scale is a 1 to 5 rating based on a hurricane's sustained wind speed. Hurricanes reaching Category 3 and higher are … There are some uncertainties about the true strength of the hurricane. The hypothesis was that the silver iodide would cause supercooled water in the storm to freeze, disrupting the inner structure of the hurricane… This scale estimates potential property damage. struction and mapping of surface wind speed, maximum 1-min sustained wind speeds, wind steadiness, and du-ration of peak winds for Hurricane Donna of 1960 that are based on observations and allow for direct com-parison of catastrophe model output to observationally based analyses. The wind speed in the hurricane reconnaissance simultaneous wind and wave data is measured at flight levels mostly between 1500 and 3100 m, but Hwang and Fan (2017) misinterpreted it as the surface (10 m) value. (These were not part of the official National Hurricane …
