The most elevated areas of Grand Bahama are red.
This is a topographic map of Grand Bahama island.
Green: 0-15 ft
Yellow: 15-30 ft
Red: 30+ ftDorian's storm surge is estimated at 18-23 ft, which would submerge everything in green and significant parts of the yellow. Hopefully most people managed to move to safe locations. pic.twitter.com/lyoFA8mPnV
