Tornadoes form in huge rotating thunderstorms known as supercells.

Thunderstorms are very common from May to September and can occasionally be quite heavy.

St. Elmo's fire is seen during thunderstorms when the ground below the storm is electrically charged, and there is high voltage in the air between the cloud and the ground.

The Committee noted that satellites could provide information on the state of the ocean and on the potential for floods and droughts or on the high numbers of intense thunderstorms.

So we went and we looked for a second free Internet tool called Wolfram Alpha, and we checked the weather reports for the day in which this video had been uploaded, and when we went through all those various cities, we found that in Florida, there were thunderstorms and rain on the day.
