MIAMI (AP) — A disorganized cluster of storms that had been plaguing the Gulf Coast for days came together to form Tropical Storm Arthur on Wednesday — the first tropical cyclone of the season in the Atlantic basin.

Flash flooding was the main threat from Arthur, a weak tropical storm that the National Hurricane Center in Miami said would be short-lived. Maximum sustained winds were around 40 mph (65 kph), with little change in strength forecast before it is expected to dissipate by Wednesday night or early Thursday.

The storm hung over coastal Texas on the same day a World Cup match was being played between Portugal and the Democratic Republic of Congo in Houston. The stadium is covered, and no plans were announced to move or reschedule the match.

National Hurricane Center director Michael Brennan said during a briefing that flash flood warnings were already being issued in the Houston metro area, with more likely to follow across the region, even after the center of the storm passes.

“The main threat from Arthur is going to be a prolonged, multiday, heavy rainfall event that could produce dangerous to life threatening flash flooding,” Brennan said.

A teenager appears to have drowned in a flooded retention pond outside Houston, authorities said Tuesday evening. A group of teens were playing near a construction zone and an adjacent retention pond when a 15-year-old boy entered the water, the Montgomery County Sheriff’s Office said on social media. Rescue workers found his body using sonar technology following an extensive search.

“This incident serves as a solemn reminder of the dangers associated with floodwaters, particularly following periods of heavy rainfall,” the post said.

Flooding was likely through Friday over parts of Texas, Louisiana, Mississippi, Alabama, Georgia and the Florida Panhandle, the hurricane center said.

The tropical storm is expected to produce rainfall totals of 5 to 10 inches (13 to 25 centimeters), with isolated higher totals near 20 inches (50 centimeters). The combination of storm surge and the tide will cause normally dry areas near the coast to be flooded by rising waters moving inland from the shoreline.

Swells generated by Arthur are likely to cause life-threatening surf and rip current conditions along the northwestern Gulf Coast for the next couple of days. Tornadoes are possible through Thursday.

The center of Tropical Storm Arthur was located Wednesday morning about 40 miles (65 kilometers) east-northeast of Port O’Connor, Texas, according to an advisory. The storm was moving northeast near 9 mph (15 kph), and an increase in forward speed was expected.
