NWS SURVEY SUMMARY:

“A national weather service storm survey determined that an EF-1 tornado, with maximum sustained winds of approximately 93 mph, moved across northwestern portions of Nassau County during the predawn hours of Thursday, April 7th.

Ef-0 damage, mostly in the form of large broken tree branches, was noted at the beginning of the tornado track just west of U.S. Highways 1/301/23 near the town of Boulougne, near the intersection with Karma Way.

The tornado then tracked east-northeastward towards the little St. Marys river, producing additional EF-0 damage in the form of tree damage, with some likely rear flank downdraft straight-line wind damage noted along Conner cutoff. The tornado reached peak intensity of EF-1, with winds peaking at approximately 93 mph, as it crossed the intersection of Conner cutoff and Murrhee roads, where trees were uprooted and large tree trunks were snapped.

A single wide manufactured home in this area experienced considerable wind damage, as its metal roof was partially torn and was lofted for a distance of about 20 yards. The tornado then lifted just east of Murrhee road, where EF-0 damage to trees was noted in swampy area.

No injuries nor fatalities have been reported from this overnight tornado touchdown.”
