Mayor: Storm surge from Hurricane Harvey to inundate much of Galveston

GALVESTON -- The mayor of the popular Texas Gulf Coast city of Galveston says the city is expected to be inundated with water from Hurricane Harvey.

Mayor James Yarbrough said during a news conference Friday that Hurricane Harvey is expected to flood downtown streets. A storm surge of 2 feet (0.61 meter) to 4 feet (1.22 meters) of water is expected to inundate much of the city while up 8 feet could cover other areas. Storm surge is an abnormal rise of water above the normal tide, generated by a storm.

He says a leading concern is that high tide will occur Saturday morning, shortly after Harvey makes landfall, and the water is not expected to recede for three or four days.

Galveston was lashed by Hurricane Ike in 2008 and Yarbrough says a difference is that Ike passed through quickly while Harvey will linger and drop substantial rainfall.

He says utility lines and other infrastructure have been upgraded since 2008 to withstand a Category 5 hurricane. Harvey is forecast to become a Category 3 by the time it makes landfall.
