Summary: Currently, some shorelines near the Bahamas and the Gulf Coast of Florida seemed bare and drained. Where have all the water gone? According to Judson Jones (CNN meteorologist), the strong wind was actually pushed the water away from the shore to further offshore. However, the scariest part would be when the wind comes back more dramatically and stronger pushing the water onshore, possibly more dangerous storm will be hitting as mentioned by Scott Hagen, director of the Center for Coastal Resiliency at Louisiana State University. So, he advised avoid putting oneself in such an unpredictable danger.
