SUMMARY: Winter Storm Watches and Winter Weather Advisories are in effect as a strong cold front approaches from the west. Sunday night through Monday night dangerous travel conditions can be expected due to water freezing on roadways.

DISCUSSION: Light drizzle/rain will begin to change over to all heavy precipitation across northwest Alabama Sunday evening and overnight. Travel is going to be very dangerous as any precipitation will quickly freeze causing slick driving conditions. There is also the potential for ice accumulations which could freeze on branches, power lines and cause power outages.

A Winter Storm Watch has now been issued for much of the Tennessee Valley. Significant ice accumulations from Sunday evening thru Monday night will translate into very hazardous travel conditions due to ice & sleet covered roadways. Limit travel if at all possible late Sunday thru Monday night & have your Winter Emergency Kit ready!
