SOME LINGERING BANDS BEYOND THAT. TEMPS WILL HAVE A HARD TIME

THE RECENT HEAVY RAIN HAS CAUSED SMALLER TRIBUTARIES TO RISE OVER
THE PAST 24 HOURS. THE TWO RIVERS RIVER AT HALLOCK IS FORECAST TO
RISE INTO MINOR FLOOD STAGE...WITH SEVERAL OTHER FORECAST POINTS IN
THE VALLEY IN ACTION STAGE. THERE HAS BEEN UPWARDS OF 4 TO 5 INCHES
OF RAIN IN WADENA COUNTY...AND AN URBAN AND SMALL STREAM FLOOD
ADVISORY IS IN EFFECT HERE. THE UPCOMING WEEK LOOKS DRY WITH SLOWLY
WARMING TEMPS...THAT SHOULD CAUSE RIVERS AND STREAMS TO RECEDE.
