SALT LAKE CITY -- A spike in temperatures means Utah's mountain-fed rivers and streams are quickly swelling -- some tripling in volume in a matter of days -- and raising the risk for those who recreate around them.
National Weather Service hydrologist Brian McInerney says winter snowmelt began in earnest on Monday.
He's warning parents to keep youngsters away from fast-moving streams. Each year, he says children fall into and drown in Utah's frigid, mountain rivers.
The danger is expected to remain high until early June.
Flooding isn't expected this spring, partly because northern Utah got less-than-average snow over the winter.
In southern Utah, where snow was more plentiful, McInerney says pre-existing channels will help keep rivers within their banks.
