Hermine's peak U.S. storm surge likely between 2 and 4 feet



Tropical Storm Hermine made landfall in extreme Northeastern Mexico yesterday evening, generating maximum sustained winds of near 65 MPH. Much of the Texas Coast experienced a strong onshore flow, with strong winds and heavy rains.

Hermine most likely produced a storm surge between 2 and 4 feet. The Corpus Christi Caller reported water levels reaching the dunes on Padre and Mustang Islands.

Quote: "Storm surges are expected to raise water levels 2 feet to 4 feet above sea level. High tides Monday were reported by the National Weather Service to have reached up to dune areas in northern parts of Padre Island and Mustang Island."

Tide gauges at South Padre Island Coast Guard Station and Port Isabel, TX, reported peak water levels approximately 1.5 feet above normal. However, given the localized nature of storm surge, it is common for the peak storm surge to occur where tide gauges are absent.

The Brownsville Herald and South Padre Island Breeze newspapers did not report any storm surge levels or surge-related damage this morning. CNN provided the picture on this blog post.

Expect surge levels and wave action to diminish throughout the day today.
