That would be a tornado. Once the process starts, a tornado can form in a matter of seconds. Hurricanes, by contrast, usually take several days to form and are easy to track.
A tornado warning is worse. It means that a tornado has been detected or the threat of one is imminent. A tornado watch means the overall conditions are favorable to form in a general area.
Any one of these can form over the ocean, but only a hurricane does so exclusively.
A hurricane and a tornado can't exactly collide as they operate on entirely different scales. A hurricane is its own storm system typically several hundred miles wide while a tornado is a relatively small scale vortex usually no more than a few thousand feet wide and is dependent on a parent thunderstorm. In fact it is fairly common for the storms in the outer bands of a hurricane to produce tornadoes.
It is not possible for a tornado and a hurricane to occur simultaneously in the same location. Tornadoes can occur within hurricanes, but they typically form in different ways and under different conditions. Hurricane-force winds can cause tornadoes to develop in the outer bands of the storm.
It depends. For storms that form relatively quickly, the warning period may be a few hours, but thankfully most storms are not like that. Usually, when a hurricane warning is issued, it means that the National Hurricane Center is expecting hurricane conditions to occur in the warning area within 24 hours. However, hurricane warnings are usually issued after hurricane watches, which specify a period of 24-36 hours from the issuing of the warning to the onset of hurricane conditions.

Partially. A tornado warning means that a tornado is likely to form or already has formed.
No. A tornado warning means that a tornado is likely to form or has already been spotted.
Yes hurricanes take a long time to form and may exist for weeks. Tornadoes on the other hand form quickly and exist for only minuets. You therefor get a longer warning about a hurricane than you do about a tornado.
Sort of. A tornado warning means that either a tornado has already formed or may form very soon.
Yes. A tornado watch simply means that general conditions are favorable for tornadoes to form. A tornado warning means that a tornado has been detected or may form at any moment.
A tornado warning is worse. It means that a tornado has been detected or the threat of one is imminent. A tornado watch means the overall conditions are favorable to form in a general area.
A tornado drill is like a fire drill but for tornadoes: practice for the possibility of a tornado. A tornado warning means that a tornado has been detected or is likely to form soon.
No, that would be a hurricane.
Tornadoes are smaller in scale compared to hurricanes and are typically embedded within them. So while a tornado can form within or near a hurricane, a direct collision between a tornado and a hurricane as two separate weather events is highly unlikely.
A tornado watch means that conditions a favorable to tornadoes to form. A tornado warning means that a tornado is present or has been spotted either by radar, spotter, law enforcement, etc.
A tornado warning is worse. It means that a tornado has been detected or the threat of one is imminent. A tornado watch means the overall conditions are favorable to form in a general area.
A tornado warning means that a tornado has already been spotted or is likely to form in the next few minutes. The tornado may be only minutes away from your location, so if a tornado warning is issued, take cover immediately.
