The National Weather Service office in Missoula has extended a flood advisory and flood warning for parts of Missoula, Granite and Powell counties.
The Flood Warning for the Clark Fork River at Drummond has been extended until 6 a.m. on Friday.
Small creeks and streams up stream of the Clark River near Drummond continue to run high from recent rainfall.
The water flowing into the Clark Fork River is expected to continue to be above minor flood stage of eight feet.
When the water reaches minor flood stage ranch land and a few out buildings are flooded between Drummond and Bearmouth.
Meanwhile, the Flood Advisory in Missoula for Kehrwald Drive and Tower Street remains in effect until 9:15 a.m. on Saturday.
Street flooding will continue on Kehrwald Drive and Tower Street in the Orchard Homes neighborhood of Missoula through at least Saturday morning.
The flooding in Missoula is the result of the Clark Fork River rising due to recent rainfall.
Flooding from streams near Deer Lodge force officials to close the Clark Street Bridge on Wednesday.
Additionally, NWS predicts that heavy rainfall from thunderstorms across southwest Montana will increase flash flooding threat for small streams.
Saturated ground will increase rainfall runoff potential as well, with excessive runoff capable of moving debris over area roads.
Some of Thursday’s storms will be capable of producing heavy rainfall and large hail, along with frequent cloud-to-ground lightning.
