Yes, of course there can be two tornadoes at the same time.
Yes, it is possible for there to be 3 tornadoes on the ground at the same time, though it is unusual for them to come close to one another.
Yes. In some of the most intense outbreaks there have been over a dozen tornadoes on the ground at the same time, though not in the same place.
Multiple tornadoes can form at the same time during a severe weather event, especially in outbreaks or supercell thunderstorms. The exact number of tornadoes that can form simultaneously can vary, but it is not uncommon for several tornadoes to be observed in the same area or region at once.
Tornadoes can form at any time of day or night. The time from 3 PM to 9 PM is the most common time for tornadoes to form.
It is extremely rare for four tornadoes to occur simultaneously in the same area. Tornadoes typically form from separate thunderstorms and are usually isolated events. Multiple tornadoes can occur in quick succession or in the same general area, but having four at the same time is highly unlikely.
A group of tornadoes occurring at the same time and location is referred to as a tornado outbreak. This can happen when atmospheric conditions are conducive to the formation of multiple tornadoes in a particular area.
Fairly often actually. It is not uncommon for multiple supercells to produce tornadoes at the same time during an outbreak. Even more often several tornadoes form and dissipate in succession, though in most cases no two are on the ground at the same time.
The record is 16 on the ground at the same time during the 18 hr "Super Outbreak" of April 3 and April 4, 1974. Total tornado count for the 18 hrs was 148.
Tornadoes are least likely to occur in the early morning, particularly from 3:00 am to 9:00 am.
They don't. While it is fairly common for a hurricane to produce tornadoes, most tornadoes are not associated with hurricanes. The thunderstorms that produce tornadoes may produce strong, even hurricane-force winds, but that does not make them hurricanes.
It is unlikely that two tornadoes could maintain such high intensity so close to each other.
