SALT LAKE CITY (ABC4) — We’re expecting record-high temperatures for the first part of the first week of May, and it’s starting to show as Utah’s record-high snowpack starts to melt along with it.

Large portions of the state are under flood and avalanche watches as the snow begins to melt. Temperatures are expected to creep into the high 80s. Drivers should not park their vehicles along streams or washes.

Also, six inches of moving water can knock you off your feet and can cause a loss of control if you are driving. A foot of water can float a vehicle. Two feet of water can carry away most vehicles, including SUVs and pickup trucks, according to the National Weather Service.

If floodwaters rise around your car, abandon it and move to safer ground.
