Written by By Maureen Farrell, CNN Many coastal cities such as Virginia Beach, Virginia, and Grand Cayman could be dealt a rude awakening if Hurricane Ida hits land — and that’s in part because of buildings’ built-in vulnerabilities. Updating maps from the non-profit Global Weather Data shows the potential locations of big swaths of the US and Caribbean, if these locations are anywhere close to storm surges, flood-
prone areas, and the sea. With its 6.6-mile diameter, Hurricane Ida could easily damage cities of anywhere from 100 to 300 miles (160 to 500 kilometers) apart from Florida to Texas. A Category 4 or 5 hurricane would result in lots of flooding, extensive damage, and — in some cases — a loss of life. At top is San Francisco, with 80% of its cities deemed at risk. To the right, Nassau, Bahamas — and almost all of its
hotels — are at extreme risk. To the left, the US Virgin Islands are on track for major damage. San Juan, the capital, is already awash with Hurricane Michael’s water and damage. But the entire British Territory, with 76% of its cities at risk, may fall in the next line of photos. To the far right, the hurricane’s wave – spinning center could easily sweep Puerto Rico, which is frequently a target for cyclones, much
like hurricanes, hit people. Just at this location, CNN’s New York office is just a few miles south and will likely deal with the brunt of the winds. “This map shows the potential extreme hurricane conditions caused by Hurricane Ida in the area stretching from Miami to North Carolina,” said Global Weather Data director and founder Gene Epstein, “The major threat to the people of Florida — including Miami and Orlando
— is storm surge combined with flooding from storms that reached Category 4 or 5 strength.” The magnitude of flooding in some locations will depend on the amount of rainfall associated with the storm, combined with the area’s flood conditions. Storms that pose a greater risk to the US typically move faster than hurricanes that strike, so the flooding will be more intense the farther north you go.
