The Atlantic Hurricane Season started June 1 and it has not let up. So far, New Jersey has felt the remnants of Hurricanes Debby and Ernesto. This year experts predicted an "extremely active ...
The most widespread hurricane-induced tornado outbreak on record was triggered by Ivan in 2004, which produced 18 tornadoes in Florida and 115 overall, killing 7.
Tornadoes often begin as funnel clouds with no associated strong winds at the surface, and not all funnel clouds evolve into tornadoes. Most tornadoes produce strong winds at the surface while the visible funnel is still above the ground, so it is difficult to discern the difference between a funnel cloud and a tornado from a distance.

The old scale lists an F5 tornado as wind speeds of 261–318 mph (420–512 km/h), while the new scale lists an EF5 as a tornado with winds above 200 mph (322 km/h), found to be sufficient to cause the damage previously ascribed to the F5 range of wind speeds.
A major whirlwind (such as a tornado) is formed from supercell thunderstorms (the most powerful type of thunderstorm) or other powerful storms. When the storms start to spin, they react with other high altitude winds, causing a funnel to spin. A cloud forms over the funnel, making it visible. [1] Minor whirlwind
Most tornadoes occur in the eastern half of a hurricane because the creation of the updraft that starts a tornado needs moisture, instability, and lift ‒ all things found on the "right" side of ...
Tornadoes can also be spawned as a result of eyewall mesovortices, which persist until landfall. [162] Hurricane Ivan produced 120 tornadoes, more than any other tropical cyclone. [163] Lightning activity is produced within tropical cyclones. This activity is more intense within stronger storms and closer to and within the storm's eyewall.
Tornadoes are common before and after hurricane landfalls. Earlier this season, Hurricane Beryl spawned 68 tornadoes from Texas to Canada. However, even that number is eclipsed by Hurricane Beulah ...
