This event is part of a larger weather pattern driven by Hurricane Isaias, which made landfall in Florida as a Category 2 hurricane on the night of October 9. The county's emergency management division is actively monitoring the situation, issuing warnings and providing resources, such as free parking garages for residents to move vehicles out of flood-prone areas.
