The storm that is expected to dump more than an inch of rain on Medford before it ends Friday morning is roiling Bear Creek to near-record flows.

The NOAA River Forecast Center has predicted Bear Creek later today will match the all-time Feb. 10 flow of 1,190 cubic feet per second, which was seen downtown in 1996.

But the peak flow will raise the creek to 5.74 feet on the flow gauge, which remains well below the 10-foot flood stage, according to the forecast center.

"That's a lot of flow," said Sven Nelaimischkies, from the National Weather Service office in Medford. "It's pretty impressive."

The atmospheric river that moved into Southern Oregon Wednesday from the Hawaiian Islands area dumped two-thirds of an inch of rain by late Thursday afternoon and was forecast to drop another four-tenths of an inch by the time it dissipates late Friday morning, according to the Weather Service.

Ashland received just shy of an inch of rain in the first 24-hours of the storm and was forecast to get another third of an inch by late Friday morning.

As with most of these storms with clouds carrying heavy loads of moisture, the Coast Range took the brunt of the rain, according to the Weather Service.

Brookings received 2.73 inches of rain in a 24-hour period beginning Wednesday, and the gauge is forecast to swell over the four-inch mark, Nelaimischkies says. That caused the Chetco River to power at more than 36,000 cfs when it peaked Thursday afternoon, but it remained within its banks.

However, the Curry County Sheriff's Office reported heavy debris loads in the Chetco as well as isolated slides.

The Rogue River was much less boisterous, but flows did bolt up Thursday to almost 9,500 cfs at Dodge Bridge where Highway 234 bisects the river near Eagle Point. The Rogue hits flood stage there at 20,000 cfs, according to the U.S. Army Corps of Engineers.

The Rogue did bump right up to, but did not eclipse, flood stage Thursday in Agness, 27 river miles east of the Pacific. Flows there were just shy of 53,000 cfs Thursday before leveling off, according to the forecast center.

As those flows slowed, the Weather Service and the Curry County Sheriff's Office canceled a flood warning for the Agness area.
