Tornado warning issued for Tri-County

Apr. 19, 2013 @ 02:29 PM

The Tri-County area has been placed under a tornado watch until 9 p.m. Friday evening, according to the National Weather Service.

The watch includes the following 25 counties: Alamance, Anson, Chatham, Cumberland, Davidson, Durham, Forsyth, Franklin, Granville, Guilford, Harnett, Hoke, Johnston, Lee, Montgomery, Moore, Orange, Person, Randolph, Richmond, Scotland, Stanly, Vance, Wake and Warren.

A tornado watch means conditions may be conducive to a tornado forming.

If one is suspected to exist, the NWS will typically then issue a tornado warning.

According to the National Weather Service website: “This is issued by the National Weather Service when conditions are favorable for the development of tornadoes in and close to the watch area. Their size can vary depending on the weather situation. They are usually issued for a duration of 4 to 8 hours. They normally are issued well in advance of the actual occurrence of severe weather. During the watch, people should review tornado safety rules and be prepared to move a place of safety if threatening weather approaches.

“A Tornado Watch is issued by the Storm Prediction Center in Norman, Okla. Prior to the issuance of a Tornado Watch, SPC will usually contact the affected local National Weather Forecast Office and they will discuss what their current thinking is on the weather situation. Afterward, SPC will issue a preliminary Tornado Watch and then the affected NWFO will then adjust the watch (adding or eliminating counties/parishes) and then issue it to the public. After adjusting the watch, the NWFO will let the public know which counties are included by way of a Watch Redefining Statement. During the watch, the NWFO will keep the public informed on what is happening in the watch area and also let the public know when the watch has expired or been cancelled.”
