How long after landfall are tropical cyclone tornadoes a threat ?
Tropical cyclones may spawn tornadoes from a day or two prior to landfall to up to three days after landfall. Statistics show that most of the tornadoes occur on the day of landfall, or the next day. The most likely time for TC tornadoes is during daylight hours, although they can occur during the night, too (Novlan and Gray 1974, McCaul 1991) . Although statistically the largest number of tropical cyclone tornadoes occurs on the day of landfall, some of the biggest and most damaging outbreaks have taken place 1 or 2 days after landfall, as with Beulah in 1967, Danny in 1985, and Beryl in 1994. In the case of Florida, with its peninsular shape, many of the tornadoes occur as the outer rainbands reach the state, well prior to the landfall of the tropical cyclone center (Hagemeyer and Hodanish 1995, Hagemeyer 1997).
