As if nearly 3 feet (0.91 meters) of rain over the next several days, up to 12 feet (3.5 meters) of storm surge and triple-digit winds aren't enough, Hurricane Harvey is also likely to spawn tornadoes.

Harvey is forecast to make landfall in Texas late Friday or early Saturday as a Category 3 storm.

The National Weather Service alerted that people to the north and northeast of Harvey's eye may experience tornadoes.

University of Miami senior hurricane researcher Brian McNoldy says tornadoes are very common during hurricanes, usually in the outer rain bands in the northeast quadrant of the storm. It's because of the way the winds blow and rotate there.
