The primary risks from Hurricane Isaias include damaging winds, flooding, and potential road closures that could hinder evacuation efforts. Wind gusts reaching 45 mph (72 km/h) may force the closure of critical bridges, leaving those who delay evacuation unable to leave. Coastal areas are particularly vulnerable to storm surge and high winds, which could cause property damage and power outages. Local officials emphasize the importance of evacuating early to avoid these hazards. Additionally, supplies such as fuel and groceries are becoming scarce in some areas, adding to the challenges for those remaining behind.
