15 damage points were recorded along this path by NWS TAE, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF1. The highest wind the damage implies is 100 mph.

• Several pine trees snapped or uprooted.
• A significant portion of roof material removed or peeled back. Some plywood loss.
• A few pine trees uprooted along Kirbo Road.
• Several pine trees snapped and uprooted along Florida Short Route.

A strong spring cold front moved through the tri-state region. A squall line preceded the front with scattered reports of severe weather, including a few tornadoes.

This tornado touched down near the intersection of U.S. Route 19 and Century Road East where a pine tree was snapped. Further east on Century Road, the tornado snapped another large pine and did considerable structural damage to the property. About 60% of the roof of well-built home was removed. A substantial carport was ripped off the home and tossed several feet. One wall segment of a large garage was sucked outward. The tornado did not do any appreciable damage to houses to the right or left of this residence. After moving over an unpopulated swamp area, the tornado snapped several softwood pines and uprooted several large hardwood trees at 669 Lovers Lane Road. The tornado crossed another sparsely populated swampy area and may have briefly lifted before uprooting more trees on Middle Road North. These were felled in crosswise fashion. The final damage area was on New York Road. A large live oak tree was uprooted and fell into a home. Several other large trees on the property were also uprooted. Just up the road, the tornado was sighted by a homeowner as it crossed their property, destroying a shed, tossing a trampoline and snapping a pine tree. The tornado then likely lifted over an open field beyond this property as no further damage was noted northeast of New York Road. Damage along the entire route was consistent with an EF-1 tornado with tops winds of 100 mph.

Lead time is measured from the issue of the warning in force to the touchdown time in the database, both of which were recorded to the minute by different people.

The Storm Prediction Center had this point in a Slight Risk, with a 0.05 chance of a tornado within 25 miles. The outlook in force was issued at 12:48 UTC.

15 more were confirmed in the United States that day.

Ratings are the survey's, read off the damage rather than measured; the rating scale is above. Tornado counts rise through the record as reporting improved, so a year in the 1950s is not comparable with one today except for the strongest tornadoes, which were always noticed.
