Area flood risk for weekend
We'll have dry conditions today and into the weekend with highs climbing above normal seasonal averages of low 60's into the mid-to-upper 70's and some will see 80's by first of May on Monday afternoon. The warmer temps are spurring the record snowpack to meltdown and this is cause for concern with localized flooding. There is a flood watch for the regional hills/mountain areas, plus flood advisories have now been issued for Blaine County and into the Sun Valley region. And with flood stage being surpassed at the Portneuf River there is a flood warning for Bannock County and areas from Chubbuck, to Pocatello and Inkom along the river. This will affect local trails and recreation areas like Sacajawea Park, as shown here. Thanks for Denver Hamm for sharing photos. Statements from the National Weather Service are show below as well. Turn around, don't drown.
