A fresh storm pounded the northern part of the metro area tonight.
Michelle Halstead, Commerce City spokeswoman, reported that a funnel cloud was sighted at 74th Avenue and York Street as the storm moved through Commerce City.
The sirens were sounded at 7:18 p.m., with an all-clear issued at 7:48 p.m., she said.
The National Weather Service said that there were no confirmed reports of tornadoes tonight, though severe thunderstorms with rotating clouds prompted some scares for residents.
The latest warning for severe thunderstorms expired at 8 p.m.
That warning covered extreme northeastern Jefferson County, western Adams County, northern Denver County and central Broomfield County.
At 7:03 p.m., Doppler radar had indicated a severe storm over central Westminster, moving east at 29 mph. The storm was capable of producing winds of 60 mph.
Heavy rains and some hail was reported.
Westminster dispatchers said that a portion of Sheridan Boulevard near 92nd Avenue was shut down briefly during the storm due to flooding.
Authorities there also fielded multiple calls on flooding basements and fallen trees, but no one was reported injured.
Thornton and Broomfield dispatchers also said they had some flooding, but no one in need of a rescue.
An urban and small street flood advisory was extended for areas of northeastern Jefferson, northwestern Adams, southwestern Weld, and Broomfield counties until 10:15 p.m.
Although rain has stopped, some streets are still heavily flooded.
The storm also caused some more delays at Denver International Airport, most about 30 minutes.
Earlier, a severe thunderstorm warning for northeastern Denver County, central Adams County and north central Arapahoe county ended at 3 p.m. today.
Afternoon rain showers fell over central Denver and the northern suburbs shortly before 2 p.m.
DIA spokeswoman Laura Coale said the public was reminded to check their flight status with their airlines or on and to use caution while driving to and from the airport.
The city of Denver warned residents today to take special precautions during storms and high water.
Among the suggestions:
— Avoid traveling if possible.
— Know that 6 inches of water can cause loss of control or stalling in most cars, one foot of water will float most cars
— Avoid driving in water that downed power lines have fallen in because the electric current runs easily through the water.
— Avoid walking through moving water because 6 inches of it can cause people to fall.
