When it comes to winter storms, ice can be particularly hazardous. Not only is freezing rain challenging to forecast, but ice storms can wreak havoc on electrical infrastructure and vegetation, knocking power out for weeks and leaving roadways impassible. Travel becomes dangerous if not impossible, with roads becoming ice rinks.

It’s the type of winter weather we see more frequently and don’t really have a tough time identifying. Snowflakes are able to reach the ground – and not turn into freezing rain or sleet – when the temperature is at or below 32 degrees from the cloud base to the ground.

By late afternoon and evening, models show freezing rain developing for areas around the Mission Valley and south. Under these conditions roads may quickly freeze over leading to very difficult travel for tonight into Saturday morning.
