The National Weather Service in Duluth has issued an urban and small stream flood advisory until 9:30 p.m. for northeastern Carlton County, south central St. Louis County including Duluth, and northwestern Douglas County including Superior.
At 6:36 p.m., thunderstorms were moving through the Twin Ports and that has led to some street flooding in west Duluth. Portions of Grand Avenue, and at the intersection of 57th Avenue West and Huntington, and at 78th Avenue and Vineland, water was flowing over the roads. The water should drain over the next hour, but more thunderstorms will move into the area between 7:30-8:30 p.m.
Other street and rapid small stream rises will be possible across the Twin Ports.

At 6:10 p.m., weather spotters reported quarter size hail and 60 mph winds in the community of Adolph. National Weather Service Doppler radar indicated the severe thunderstorm was capable of producing quarter size hail and damaging winds in excess of 60 mph. This storm was located near Adolph, or 6 miles west of Duluth and moving southeast at 30 mph.
The severe thunderstorm will be near Gary New Duluth, New Duluth, Duluth and west Duluth around 6:20 p.m., Oliver around 6:25 p.m., Superior around 6:30 p.m., South Range around 6:45 p.m., Wentworth around 6:55 p.m.
The most severe portion of the storm will affect the western half of Duluth and Superior.
Tornado warnings for southwestern St. Louis, northeastern Aitkin and southeastern Itasca counties expired at 4:45 p.m., according to Amanda Graning, meteorologist with the National Weather Service in Duluth.
Duluth was never under a tornado warning, she said, even though sirens were activated after 4 p.m. Assistant Duluth Fire Chief Richard Mattson said Duluth sirens were sounded in error when the system was located between Meadowlands and Alborn, but he said the storm was headed toward the Twin Ports and residents would benefit from the advance warning.
The storm is predicted to move through Cloquet, Hermantown and west Duluth starting at about 5:30 p.m. The thunderstorms are no longer considered tornado-producing, Graning said, although a funnel cloud had been reported near the town of Goodland, 14 miles east of Grand Rapids at 4 p.m.
The entire state of Minnesota is under a severe thunderstorm watch until 10 p.m. More storms are expected in the Duluth area this evening.
