SEASIDE, Ore. -- Here comes the rain again.

Heavy rains and tidal conditions have caused high water on U.S. Highway 101, restricting the highway to high-profile and emergency vehicles. Use alternate routes.

Travelers detoured by the restrictions on Hwy. 101 need to use a detour that follows Oregon 202 to Oregon 103 and U.S. 26.

The National Weather Service predicts flooding on the Nehalem River, which could affect the detour route if conditions worsen.

101 closed at Nehalem

NEHALEM, Ore. (AP) — U.S. 101 through Nehalem is closed by high water, but Tillamook County sheriff's deputies say detours are in place.

Tillamook County sheriff's Lt. Andy Long said water could rise further when high tides come in at mid-morning Thursday.

The area has several rivers that drain the Coast Range and is prone to flooding, especially when Coast Range snow melts quickly and tides are high. The highway was closed Thursday morning.

The area did not get the heavy overnight storms that had been predicted.

I-5 expected to flood near Centralia, Wash.

The National Weather Service says the Chehalis River at Centralia could reach a record flood level Thursday night, 10 feet above flood stage.

Forecasters say the water will be deep enough to inundate residential and business areas and Interstate 5.

The Transportation Department says portions of I-5 in Lewis County could go under water as soon as Wednesday afternoon. Crews are monitoring the flooding and preparing to close the highway if it becomes unsafe.

The interstate was closed for four days at Centralia during the flooding of December 2007.

Weather disrupts schools, puts coast on alert

The Seaside School district sent its students home at noon Wednesday.

Highways through Tillamook County on the north coast were reported clear Wednesday morning but officials are concerned about the Nehalem river near Nehalem, which is expected to crest at 14 feet above flood stage Wednesday.

Tillamook County Sheriff Todd Anderson said the Nehalem-area flooding could affect lowland dairy farms and could close Oregon 53 and that the river could cover U.S. 101 at Nehalem during high tides.

Weather is expected to change to partly cloudy across most of the state over the weekend.
