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.
