A mid afternoon storm that brought heavy rain was followed later by another line that brought more rain that fell in torrents at times and thunder and lightning.
One tornado was spotted on the ground a mile north of Underwood and others were seen about three miles northwest of Cannonball near the Cannon Ball River, a mile west of Beulah and reported 10 miles east of Halliday, National Weather Service meteorologist Tony Merriman said.

A tornado and high winds north of Wellington have blown vehicles off roads and injured several people.
The twister hit 1.5km north of Waikanae on the Kapiti Coast about 4pm, police central communications Inspector Paul Jermy said.
Several people were believed to have been injured, including a woman who was taken to Wellington Hospital after an uprooted tree crushed the caravan she was in.
Another person had to be rescued from their home after a tree fell on it, trapping them inside.
Mr Jermy said a man suffered minor injuries to one hand after the tornado toppled a van on State Highway 1.
It also lifted a roof or shed of a nearby property and blew debris onto the road, he said.
A worker attached to the road widening project taking place in the area had been buried under the mound of earth along with two bulldozers. Thankfully, the worker had been rescued by other workers who had witnessed their colleague getting buried under the huge mountain of earth. The man was taken immediately to the Attampitiya hospital for medical attention. Police said the two bulldozers had also been badly damaged but that the drivers had escaped unhurt.
OIC Attampitiya police SI U.M. Chandrasena advised the drivers to use the Badulla- Bandarawela through Hali- Ela to reach Welimada until the main road was cleared of debris. Police however warned that progress was slow as mounds of earth were still coming down.

Two girls brave the rushing floodwaters Friday afternoon to walk along the path and through the covered bridge in Baker Park. Much of the park was covered by the heavy rain.
The brunt of the rain, 1.2 inches, fell between 3 and 3:30 p.m., said Paul Walker, senior meteorologist with AccuWeather.
The sudden rainfall overloaded the city's drainage system and flooded streets, said Chip Stitley, superintendent of stormwater and sanitary sewer for the city's Department of Public Works.
The floods were concentrated in the City of Frederick, said Steve Leatherman, technical services bureau chief for the Frederick County Division of Fire and Rescue Services. Parts of Highland, East Church, Patrick and Market streets, among other roads, were closed for short periods, he said.
"It was a situation where water flooded the roads and then receded," Leatherman said.

One of the worst hit areas was Balcarres Street in Morningside, where the flooding began just after 2.40pm. Shaun Robertson, 22, and Lee Craig, 26, both painters and decorators, were trapped in their van in the middle of the road for over an hour.

Cars are stranded on Mill Creek Road in New City after Friday's heavy rain.
The thunder could be heard and the lightening seen as early as 2:30 p.m. in some areas, but the brunt of the storm didn't move across the county until about 4 p.m.
Heavy rains caused flash floods in some places, and heavy winds downed trees in others. That left some county roads impassable.
Friday evening, hours after the rains eased and the flood waters receded, Melvin and Marilyn Israel stood at the entrance to their Mill Creek Road home in New City, listening as workers pounded nails into their roof to secure a tarp.
Beneath the tarp, a gash had been left by a massive tree that had fallen.
