|Lycoming County Tornado Damage 5/11/03|
A weak tornado occurred near Cogan Station late in the afternoon of 5/11/2003
Residents in the area reported that they saw funnel clouds, and the folks at the farm below heard of the tornado warning from a relative in a nearby town who was concerned about their safety. They took shelter, and heard the winds shortly after.
To keep informed during severe weather (and all year 'round), listen to NOAA Weather Radio (the voice of the National Weather Service) and get your warning and forecast information directly from the folks who issue the warnings! Most NOAA Weather Radios will activate an audible alarm when your National Weather Service issues a Severe Weather Warning.
