Waterwise Wednesday: Gutter check

Continued melting means flowing snow melt and runoff. Check street gutters and storm drains near your home to make sure they’re clear of debris and functioning properly.

Clogged storm drains can cause neighborhood flooding, icy back up and nutrient overload as debris decays in the drains.Removing leaves, one of the largest urban sources of phosphorus pollution, from street gutters and drains can reduce the amount of phosphorus in urban runoff by 80% (USGS 2016).

Waterwise Wednesday: Snow Science

Cloudy winter days make the snow melt faster, says a study from the University of Utah. Snow is designed to stay cold in three ways: by deflecting the sun’s heat with it’s bright white color and crystalline structure, the bright white reflecting heat back at night, and sublimation, evaporating from snow to vapor, similar to the way sweat evaporates from our skin to keep us cool.

Cloudy humid days, however prevents snow from deflecting, reflecting and sublimating warming the snow. That is why a few humid days with temperatures hovering around the freezing point create large melt events and even minor flooding.

Do your own experiment by watching snow that remains in shadows even on warm sunny days. Then watch what happens to that same snow during gray days and nights — quickly, though, before it’s all gone.
