Hurricane Isaias Won’t Hit Galveston, But It’s Bringing Dangerous Gulf Conditions to the Island

GALVESTON, Texas — Hurricane Isaias is not expected to make landfall in Galveston or directly impact Southeast Texas, but residents and visitors along the island’s coast are being warned that the storm is already producing dangerous conditions in the Gulf.

The National Weather Service Houston/Galveston office says Isaias will track well east of the region. Even so, its effects are being felt along the Upper Texas Coast through increasing Gulf swells, gusty winds, dangerous rip currents and above-normal coastal water levels.

For Galveston, the biggest concern today is the water rather than the storm’s center.

High rip-current risk covers Galveston Island

The National Weather Service issued a High Rip Current Risk for Galveston Island and other Gulf-facing beaches through late Friday night.

Forecasters say the risk of strong rip currents will increase Thursday and Friday and could potentially be extended into Saturday. Rip currents can pull even experienced swimmers away from shore and into deeper water.

The National Weather Service recommends swimming near a lifeguard and staying away from rocks, jetties and piers. Anyone caught in a rip current should avoid trying to swim directly against it. Instead, swimmers should remain calm, float and, when possible, move parallel to the shoreline to escape the current.

For beachgoers, that means conditions can be hazardous even if the sky over Galveston looks relatively calm.

Small craft advisory is in effect

The National Weather Service also has a Small Craft Advisory in effect from 7 a.m. Thursday through 1 a.m. Saturday for Upper Texas coastal waters, including the waters adjacent to Galveston.

Forecasters are expecting northeast winds of 15 to 25 knots, with gusts up to 30 knots, along with elevated seas. The broader marine forecast calls for seas of 5 to 9 feet across portions of the Upper Texas coastal waters, with conditions becoming more hazardous offshore.

The National Weather Service specifically warns inexperienced mariners, particularly those operating smaller vessels, to avoid navigating in these conditions.

Conditions are expected to worsen into Friday before gradually improving later in the weekend. The latest marine forecast says winds and seas should begin decreasing late Friday into Saturday, although offshore seas may remain hazardous into Saturday.

Isaias is staying east of Galveston

The important distinction for Galveston residents is that Isaias is not currently forecast to strike the island.

As of Thursday morning, the National Hurricane Center said the hurricane was moving east-northeast over the Gulf and was forecast to make landfall farther east along the northern Gulf Coast. The Associated Press reported Thursday that Isaias had maximum sustained winds of about 85 mph and was expected to strengthen before reaching the Gulf Coast.

The National Weather Service Houston/Galveston office says no significant direct impacts are expected for Southeast Texas from the storm itself. Instead, Galveston is dealing with the storm’s fringe effects, particularly on the Gulf and along the shoreline.

That distinction matters because the conditions on the island can become dangerous without Galveston being in the hurricane’s forecast track.

What Galveston residents should watch today

For people heading to the beach, the primary concern is the rip-current risk.

For boaters, fishing operators and other mariners, the concern is the combination of stronger northeast winds and elevated seas.

And for residents in low-lying coastal areas, the National Weather Service is watching above-normal water levels and the potential for minor coastal flooding as the storm passes to the east.

The local National Weather Service forecast remains warm and generally dry on land Thursday, with temperatures expected to climb into the upper 80s and lower 90s across the region. That relatively pleasant weather could make the marine and beach hazards less obvious to people on the island.

The bottom line for Galveston

Isaias is not a direct hurricane threat to Galveston based on the current forecast, but that does not mean the island is unaffected.

The storm is already contributing to a dangerous Gulf environment, and the National Weather Service is specifically warning of strong rip currents along Galveston Island through Friday night.

Anyone planning to spend time in the surf should check the latest beach conditions before getting in the water. Boaters should pay close attention to the Small Craft Advisory and avoid heading offshore in hazardous conditions.

Galveston City News will continue monitoring conditions and any changes to beach operations, coastal flooding, boating conditions or local advisories as Isaias moves across the Gulf.
