Tornadoes often form in the right front quadrant of hurricanes as they make landfall as well.
A location for the sighting is normally given in a warning. Stay tuned to a local radio or television station or listen to NOAA Weather Radio at 162.475 MHz. Secure any loose objects outdoors, or move them inside. Survey local structures for the most suitable shelter. Keep watching the sky to the south and southwest.
