St. Croix rise forecast to crest Saturday

STAFF REPORT

The St. Croix River was up to nearly 86 feet late this morning and is forecast to crest just below flood stage sometime Saturday, according to the National Weather Service.

The St. Croix was at 85.94 feet shortly before noon today, the NWS reports. The river is expected to crest at slightly more than 86 feet Saturday, the NWS adds.

The high water led the state Department of Natural Resources Thursday to issue a slow no wake order for boaters on the St. Croix until further notice to protect against shoreline erosion.

Washington County remains under a flood warning at Lock and Dam No. 2 on the Mississippi River near Hastings. Runoff from May rainfall in the Mississippi River basin is causing backwash from the Mississippi to raise the level on the St. Croix River, according to an NWS hydrologist.

And with showers and thunderstorms in the weekend forecast, the NWS urges residents along the Mississippi and St Croix rivers to monitor the high water situation.

"Scattered showers and isolate thunderstorms Friday night and again on Sunday will add, on average, up to an additional one-quarter of an inch of moisture to the river basins," said an NWS statement. "Any significant additional rainfall may case river levels to rise higher than currently predicted."

The St. Croix Valley forecast calls for a sunny day today with highs near 70. It will be partly cloudy and cool tonight with lows near 50.

Saturday will again be sunny and mild with a high near 72. However, forecasters said there is a slight chance of showers and thunderstorms, mainly after 1 p.m. Saturday night will be clear and mild with a low near 53.

Sunday starts out sunny and warmer with highs near 80, with a 30 percent chance of afternoon and evening showers and thunderstorms and a low near 60.

Sunshine and warmer temperatures return for the start of the week with highs in the low 80s Monday and Tuesday and lows near 60.
