Sunday, stay weather-aware as afternoon showers and storms develop. Some downpours and slow-moving rain clusters could lead to street flooding. The rain and risk for flooding will continue through the early week. Remember, never drive through high water.
Stormy set-up begins 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.”
Moisture headed to southeast Texas:
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.
