CHARLESTON, S.C. (WCBD) – The Emergency Operations Center in Charleston has issued a Code Yellow for area bridges as sustained winds from Hurricane Dorian reach 35 mph.
This means high profile vehicles will be advised not to use high span (65 feet or higher) or exposed bridges, and the public should use extreme caution if they decide to travel over bridges.
The Charleston County Emergency Operations Center (EOC) works closely with law enforcement officers to receive updates on wind speeds on the various bridges throughout the County during an emergency situation, like a hurricane or tropical storm.
Condition Yellow: 30 MPH sustained winds
When the EOC receives reports from law enforcement officers that sustained wind speeds have reached 30 mph, the media will be asked to put out a message to the public that high profile vehicles will be advised not to use high span (65 feet or higher) or exposed bridges, and the public should use extreme caution if they decide to travel over bridges.
High profile vehicles are:
- Box-type trucks similar to those operated by the United Parcel Service (UPS)
- Motor homes
- Vehicles pulling travel trailers, box-type trailers, large sailboats or other watercraft
Condition Red: 40 MPH sustained winds
When the EOC receives reports from law enforcement officers that sustained wind speeds have reached 40 mph, the media will be asked to put out a message to the public that high span (65 feet or higher) or exposed bridges are unsafe for public travel. At these wind speeds, law enforcement officers may not be present at bridges due to unsafe conditions. Anyone who drives over bridges against the advisory is doing so at their own risk.
According to the county, motorists are warned that in addition to the measured sustained wind speeds, there could be unexpected and dangerous wind gusts of higher speeds.
