Extreme Water Levels during the 2020 Hurricane Season
Summary
The 2020 hurricane season was the busiest, most impactful season in the Atlantic with a record-breaking 30 named storms. NOAA's Center for Operational Oceanographic Products and Services (CO-OPS) tracked the water levels during these storms in real-time through CO-OPS’ Coastal Inundation Dashboard web mapping tool. This tool allows users to monitor elevated water level conditions along the coast when a tropical storm or hurricane watch or warning is issued.
Throughout the season many CO-OPS water level stations measured record or near-record water levels. Most of the significant water level events were recorded during four storms: Hurricane Hanna, Hurricane Laura, Hurricane Sally, and Hurricane Zeta.
