MARTIN COUNTY, Fla. -- There is little visible damage from rain storms and tornado warnings that developed overnight, affecting parts of Martin and St. Lucie Counties.
The first tornado warning was issued about 1:45 a.m. for parts of St. Lucie and Martin County, even though there had been no previous watches or storm warnings in those areas.
And by about 2:34 a.m., a second tornado warning was issued for Martin County, which expired without any sightings.
The Martin County Sheriff's Office reported a tree down across Allapattah Road, just north of Indiantown, in an area where the National Weather Service office in Melbourne had seen a "signature" of a possible tornado on its radar site during the initial warning period. But there was no other visible damage when Christina Mora and her WPTV videographer checked out that location.
The same was true in a area along Martin County Road 76, where the National Weather Service also saw the "signature" of a possible tornado on its radar. But there was no visible damage in that area.
The last warning expired at 3:15 a.m., though rains continued to fall across much of South Florida until the morning rush hour.
