As storms and triple-digit "feels-like" heat rolls through Houston on Sunday, FIFA organizers say they are ready to clear the FIFA Fan Festival if lightning gets too close.

In a statement provided to KPRC 2, a spokesperson with the FIFA Houston Host Committee, 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." KPRC 2 Chief Meteorologist Anthony Yanez said the heat index could again hit the triple digits Sunday as Southeast Texas shifts into a stormier pattern.

Storms are expected to increase around noon, with the peak window for lightning and heavy rain from about 2 p.m. to 8 p.m. The forecast also includes a 60% chance for lightning around Houston Stadium (which locals know as NRG Stadium), making weather monitoring especially important for visitors not used to how quickly conditions can turn dangerous in Houston.
