As of December 21, 2012 there are no known tornadoes currently on the ground. However it is difficult to type an answer on "current tornadoes" as most tornadoes last just a few minutes and some last only a few seconds. On top of that, it can take a while to confirm that a tornado actually did touch down.
The current of a tornado typically flows in an upward direction, carrying debris and causing damages like roof uplift and structural collapse.
No, an updraft is not the middle of a tornado. An updraft is the rising current of air within a storm or tornado that fuels its rotation and strength. The middle of a tornado is called the "eye," which is a calm and clear area surrounded by the rotating winds.
The April tornado record in the US for a whole year is 267 tornadoes, which was set in April 2011. This month had an extremely active tornado season, particularly across the Southeastern United States.

A tornado watch is a weather advisory that means that current weather conditions are favorable for tornadoes but no specific area is in imminent danger. If a tornado watch is issued pay close attention to the weather advisories and maybe keep a weather radio handy. If a tornado warning is issued seek shelter immediately.
There probably will be eventually, as Houston is in a fairly tornado-prone area and has been hit before. However, there is no way of knowing when such an event will occur.
Tornadoes cannot be prevented. Current technology can warn us of an approaching tornado, but can't do anything to stop it.
If you mean to ask if one tornado can form after another has dissipated, yes. Supercells, the storms most likely to produce tornadoes, often go through cycles. They can spawn can spawn multiple tornadoes one after another in what is called a tornado family. Sometimes the next tornado in the family will form before the current one has dissipated, resulting in there being two tornadoes at the same time.
I do not have real-time data, but tornadoes can occur throughout the year in different parts of the world. The most recent tornado would need to be checked with a current weather database or news source.
I do not have real-time data on tornado occurrences. Tornadoes can happen anytime, but the peak season varies by location. I recommend checking with local weather authorities or using online resources for the most current information.

Probably not. As of my writing this, there are no active tornado warnings in the United States, but that could change by the time you read this. For actual up-to-date information check out the website of the National Weather Service for current weather watches and warnings in the US.
