ISS captures lightning illuminating Nebraska sky from space

A camera onboard the International Space Station captured a lightning storm near Omaha, Nebraska on Sept. 13.

The station recorded the weather event as it passed over the U.S. Midwest. 

The National Weather Service had issued a "special weather" alert along the Nebraska-Iowa border, forecasting frequent lightning. 

According to NWS, frequent lightning is "lightning at the rate of 4 to 11 flashes per minute (about 20 to 55 flashes per 5 minutes) associated with a given lightning storm."

This footage, recorded from a NASA feed by @ISSAboveYou, shows lightning illuminating the sky near Omaha. Nearby Lincoln, Nebraska, is also visible.

Meanwhile, Tropical Storm Nicholas slowed to a crawl over southeastern Texas and southwestern Louisiana Tuesday after blowing ashore as a hurricane, knocking out power to a half-million homes and businesses and dumping more than a foot of rain along the same area swamped by Hurricane Harvey in 2017.

Nicholas could potentially stall over storm-battered Louisiana and bring life-threatening floods across the Deep South over the coming days, forecasters said.

Nicholas made landfall early Tuesday on the eastern part of the Matagorda Peninsula and was soon downgraded to a tropical storm. It was about 50 miles east of Houston, with maximum winds of 40 mph (65 kph) as of 4 p.m. CDT Tuesday, according to the National Hurricane Center in Miami. However, weather radar showed the heaviest rain Tuesday afternoon was over southwestern Louisiana, well east of the storm center.
