Tropical Storm Arthur Is Flooding the Gulf Coast Right Now – Is Your City in the Danger Zone?
The Gulf Coast is under siege tonight.
Tropical Storm Arthur, the first named storm of the 2026 Atlantic hurricane season, formed off the Texas coastline Wednesday morning and is already dumping catastrophic rainfall across millions of homes. Flash flood emergencies are active from Houston to New Orleans. And forecasters say the worst is still coming.
Here is everything you need to know right now.
What Is Tropical Storm Arthur and How Bad Is It?
A disorganized cluster of storms that had been plaguing the Gulf Coast for days came together Wednesday to form Tropical Storm Arthur, the first tropical cyclone of the 2026 Atlantic season. Kitsap Daily News
Maximum sustained winds are near 45 mph, and the storm is moving northeast at 9 mph. Arthur is expected to hug the coastline Wednesday and begin moving inland Wednesday night, weakening after it leaves the Gulf and moves over Louisiana. CNN
Do not let the relatively weak wind speeds fool you. This storm does not need to be a hurricane to be deadly.
Arthur’s biggest threat is a massive shield of tropical moisture capable of unleashing devastating flash flooding across eastern Texas, Louisiana, and the wider Deep South. Kitsap County DEM
Which Cities Are in the Danger Zone Right Now
The storm is expected to produce rainfall totals of 5 to 10 inches, with some isolated totals reaching up to 20 inches through early Friday from the Texas and Louisiana coasts into central Louisiana, parts of Mississippi, Alabama, Georgia, and the Florida Panhandle. CNN
A flood watch is now in effect stretching from Beaumont, Texas, all the way to Atlanta. Between 2 and 4 feet of storm surge is possible from Port Bolivar, Texas, to Morgan City, Louisiana. CNN
Here is where the threat is most severe right now:
Immediate danger, Texas: Houston metro is already flooding. National Hurricane Center director Michael Brennan confirmed flash flood warnings were already being issued in the Houston metro area, with more warnings likely to follow across the region even after the center of the storm passes. The storm hung over coastal Texas on the same day a World Cup match between Portugal and the Democratic Republic of Congo was being played in Houston, though the covered stadium was unaffected.

Tonight into Thursday, Louisiana: By 7 a.m. Thursday, the storm will bring heavy, potentially flooding rain to the Baton Rouge area. New Orleans Mayor Helena Moreno and city officials urged residents to take the storm seriously during a news conference Wednesday afternoon. Kitsap Daily News
Thursday through Friday, Alabama, Mississippi, Georgia: The storm will bring heavy rain from Atlanta to Montgomery to Mobile, Alabama by 8 p.m. Thursday. Kitsap Daily News
The Human Cost Is Already Starting
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 when a 15-year-old boy entered the water. Rescue workers found his body using sonar technology following an extensive search. Kitsap Daily News
“This incident serves as a solemn reminder of the dangers associated with floodwaters, particularly following periods of heavy rainfall,” the Montgomery County Sheriff’s Office said. Kitsap Daily News
What You Must Do Right Now If You Are in the Path
Do not wait until the water starts rising. Every minute matters in a flash flood situation.
If you are in Texas, Louisiana, Mississippi, Alabama, or the Florida Panhandle:
Never attempt to drive through flooded roads. Six inches of fast-moving water can knock a person off their feet. Two feet can float most vehicles. Obey all road closures immediately.
Move valuables, documents, and medications to higher floors in your home now, before the rain intensifies. Charge all phones and devices immediately. Download your local weather service app and enable emergency alerts.
Isolated weak tornadoes are possible through Thursday night across southeast Texas, southern Louisiana, and southern Mississippi, so this is not only a flood threat. CNN
Tropical storm warnings remain in effect for portions of Louisiana and Texas, and beachgoers should be aware of dangerous surf conditions along northern Gulf Coast beaches. A high risk of rip currents continues, creating potentially life-threatening swimming conditions. YouTube
How to Get Real Alerts, Not Viral Misinformation
Storms like this always trigger a wave of fake warnings and exaggerated posts on social media. You saw it with the Washington “Super Storm” alert that went viral earlier this year. Do not share anything that does not come from an official source.
Verified sources to check right now:
- National Hurricane Center: nhc.noaa.gov
- National Weather Service: weather.gov
- Your county emergency management website
- Wireless Emergency Alerts on your phone, make sure these are turned ON
The National Hurricane Center’s Brennan said: “The main threat from Arthur is going to be a prolonged, multiday, heavy rainfall event that could produce dangerous to life-threatening flash flooding.” That warning is as serious as it gets. Kitsap Daily News
What Comes After Arthur: Hurricane Season Is Just Starting
NOAA is forecasting a below-average hurricane season overall, with expectations for 8 to 14 named storms, 3 to 6 hurricanes, and up to two major hurricanes reaching Category 3 or higher. YouTube
El Niño, which has now been officially confirmed, is a key factor in keeping this season below average. El Niño typically reduces Atlantic tropical cyclone activity due to stronger upper-level winds that can disrupt storm formation. YouTube
But Arthur is proof that even a below-average season can produce deadly storms. The question is never whether a storm will hit, it is whether you are ready when one does.
