Tropical Storm Helene is expected to strengthen into a Category 3 hurricane as it approaches Florida's Gulf Coast, with potential storm surge reaching up to 15 feet near landfall in the Big Bend area. Evacuations may be ordered for affected counties as hurricane watches blanket the west coast of Florida, including Tampa Bay. The National Hurricane Center warns that impacts will extend well beyond the storm's center, bringing strong winds, heavy rains, and significant flooding risks across the region. Residents are urged to prepare for life-threatening conditions, including possible flash flooding, and to secure outdoor items. The storm's size and speed could result in widespread power outages and hazardous travel conditions. Authorities emphasize the importance of following updates and evacuation orders as preparations continue ahead of Helene's expected landfall on Thursday.
