UPDATE AS OF 6/17/2026 @ 1:30 PM
Current local impacts remain minimal; according to the Harris County Flood Warning System, the maximum rainfall over the last 6 hours in Deer Park is only 0.68 inches, recorded in the northern part of the city. The National Weather Service has upgraded the disturbance in the Gulf to a Tropical Storm. Tropical Storm Arthur is the first named storm of the 2026 Atlantic Hurricane Season.
According to the National Hurricane Center, Tropical Storm Arthur is expected to move across the upper Texas coast and into Louisiana this evening. While the heaviest downpours from this morningβs coastal convergence zone are weakening, additional scattered showers, thunderstorms, and localized street flooding remain possible south of I-10 through the afternoon, along with wind gusts of 20 to 30 mph (and up to 40 mph in passing squalls). As Arthur exits tonight, building high pressure will rapidly shift our focus to extreme heat, with heat index values soaring between 102 and 108 degrees on Thursday and up to 112 degrees by Friday, likely requiring official heat advisories.
