Multiple round of showers and thunderstorms ahead of a strong cold front affected the tri-state region during the April 9-10 period.  An initial round of storms on April 9th brought primarily large hail to the region, and then a squall line pushed through on April 10th with primarily damaging winds as well as a few tornadoes, mainly across Florida.  Some flooding was also reported, mainly across Florida where the heaviest rainfall amounts occurred in a short period of time.

A tornado touched down in the vicinity of Crowder Chapel and Hinote Roads near the Shoal River. Several large trees were snapped or uprooted in this area. The tornado then moved east northeast snapping and uprooting several more trees along its path. One property on County Highway 1084 sustained roof damage to the primary residence, a well-built single family home. A large metal building system on the property had large garage doors blown in with subsequent uplift and removal of a substantial portion of the roof. A small garage was also destroyed. A bit further down the highway, another metal building system had a portion of its roof rolled back. The tornado lifted near County Highway 83 just south of Glendale. Damage was consistent with an EF1 tornado with maximum estimated winds around 95 mph.

A tornado came ashore near Laguna Beach and heavily damaged a convenience store and a home. This was where the heaviest damage occurred. The convenience store roof was completely torn off of the building and lofted into a nearby house. The concrete block exterior walls were also partially collapsed. It appeared that at least some effort had been made to strap the roof to the walls of the structure, making this damage reflective of an EF2 rating with maximum winds of 125 mph. Behind the convenience store, a house was heavily damaged with portions of the roof missing, but most of the damage to this home came from the roof of the store landing on it. A projectile piece of wood was observed lodged in the side of another nearby home. Several surrounding homes also had minor roof damage, glass breakage, and fencing damaged or torn down. Another home had a carport structure completely collapsed and a wooden shed blown over and rolled into a fence.

Damage was widespread across Lynn Haven Parkway as a line of storms pushed through the area. Despite there being damage well south of the estimated path, much of this damage is estimated to come from straight line winds associated with the squall line. Roof damage to Haney Technical Center and a blown over semi on the Parkway were observed and consistent with these straight line winds. Damage just south of 14th street near the estimated path, including the greatest damage to Grease Pro Express, was found to be consistent with that of a strong EF1 tornado. At that location, the roof was lifted upwards and displaced/rotated about 30 degrees. Similar, but less intense damage, was found at homes near the Grease Pro Express. Outside of this location, minor roof damage was observed at many locations, but none of this damage was consistent with a tornado and the estimated duration of the tornado was very brief, 3 minutes at most. Maximum winds were estimated to be 105 mph.
