* Damage to weak or rotting trees can be expected. Outdoor Christmas displays may be blown about if they are not properly secured. Difficult driving conditions are expected with winds of this magnitude... especially for higher profile vehicles.
Precautionary/preparedness actions...
Wet grounds due to rains may allow smaller or loosely rooted trees to uproot due to the high winds. Unsecured patio or outdoor placements may be prone to damage from tumbling. Travel will be difficult... especially for high profile vehicles. The combination of wet roads and high winds means Holiday motorists should be extra cautious and allow plenty of time to reach your destination.
Special Weather Statement
Statement as of 9:30 AM CST on December 24, 2009
... Wet roads and full ditches leading to dangerous driving conditions...
Moderate to heavy rainfall... combined with poor drainage... has caused many ditches to become full across southeast Missouri... southern Illinois... and far west Kentucky this morning. Though no flooding has been reported... full ditches are causing deep puddles along the edges of some roadways. These puddles... and also areas of heavy rainfall... will lead to increased hydroplaning danger across the region through the day. Use extra caution on this busy travel day by slowing down... and be alert for water hazards on area roads.
