Ware Mechanical alert: Tuesday night forecast — severe weather likely; tornadoes unlikely (but possible).
Some of the slides used in the latest briefing from the National Weather Service indicate the chances of tornadoes here are remote but we can expect high winds and occasional heavy rain. The slides were part of an early afternoon presentation to emergency officials, weather experts and others.
From Tim Herrington, Floyd’s emergency management director: Thunderstorms affect relatively small areas when compared with hurricanes and winter storms. Despite their small size, all thunderstorms are dangerous because they can produce strong winds, lightning, tornadoes, hail and flash flooding. The typical thunderstorm is 15 miles in diameter and lasts an average of 30 minutes. “Straight line winds can reach speeds excess of 100 mph and produce damage similar to a tornado,” said Herrington. The biggest threat from severe thunderstorms is damaging straight line winds and large hail. These winds occur, on average, 19 days per year in Georgia. They occur in every month of the year, but are most common in the spring and summer months, peaking in July. Expanded release.
