Widespread rain is not expected until Sunday. Anyone spending time outdoors, especially at large gatherings, should take precautions and stay hydrated. If lightning occurs near Fan Fest in Downtown Houston people will have to exit the facility.

This is what the FIFA World Cup Houston Host Committee press office said, “HPD and HFD are monitoring weather at FIFA Fan Festival, and if there is lightning detected within an eight-mile radius, fans will need to exit the grounds and move to a safe location. Following a 30-minute period without any additional lightning detected within that radius, the gates will reopen. The 30-minute clock will restart with each lightning strike within that eight-mile radius.”

This goes for Sunday too.

Recognizing the signs of heat illness:

The free FIFA Fan Festival is outdoors with giant screens, food, and a 7v7 synthetic turf field for pickup games. I was there Thursday and I’ll tell you there isn’t much shade. There are misters but that’s it. Water is free so stay hydrated and try not to overexert yourself. Below are the signs of heat exhaustion. If this happens to you get help immediately. Officials have already treated dozens of fans and a handful had to go to the hospital for heat illness treatment.

Sunday’s forecast:

A low-pressure system in the Bay of Campeche is expected to funnel deep, rich tropical moisture into the area beginning Sunday. Even though the chance of this system developing into a named tropical storm is small, rainfall totals could still be significant with or without a name.

The city’s World Cup festivities, including the highly anticipated Germany vs Curacao match at Houston Stadium, are falling right in the window of this weekend’s active weather pattern. There’s a chance of a passing shower in the morning, but storms are forecast to ramp up starting around noon. The peak window for lightning and heavy rain is expected between 2 and 8 p.m. There’s a 60% chance for lightning around Houston Stadium and scattered storms throughout Southeast Texas, making weather monitoring especially important for visitors who aren’t used to how quickly our weather can become dangerous in Houston.
