Straight-line winds were the order of the day for the Charleston area from an intense squall line that moved through the Southeast yesterday.

Despite several tornado warnings, surveys from the Charleston forecast office have yielded all straight-line wind damage. (There have been at least three tornadoes confirmed by the Columbia office as of this writing, though.) In all, the Charleston weather forecast office has issued over 150 storm reports from yesterday’s event for its county warning area (which includes southeast Georgia). Here are some of the fairly notable ones:

• 81 MPH gust reported at the Charleston Branch Pilots Association just ahead of the squall line at 2:51 PM. (The anemometer is sited about 80 feet up.)
• 68 MPH gust was measured at the WeatherFlow Shutes Folly sensor around 2:55 PM.
• 63 MPH gust was measured by a docked NOAA ship at 2:55 PM.
• A tractor trailer was blown over on the Don Holt Bridge by strong non-thunderstorm winds around 1PM.

• Several reports of downed trees in Planters Pointe and Dunes West in Mt. Pleasant. A NWS employee near there reported a limb through a car windshield.
• Someone on James Island had a mailbox blown away.
• A couple trees went down on I-26 around Ridgeville and Harleyville.
