⚠️This flooding event will be a marathon - not a sprint. Potentially historic rainfall is expected through this weekend (April 3-6) from the Ozarks into the Mid-South, Middle Mississippi Valley, and Lower Ohio Valley. Any flash and riverine flooding across these areas will have the potential to become catastrophic and life-threatening.

A Flood Watch (shown in the map) is in effect across portions of TX, OK, MO, AR, MS, TN, KY, IL, IN, OH, and WV for the remainder of this week and on into the weekend.

“The stark, surreal beauty of this place and this time of transition is unlike any other.” - Ian Crocker, South Pole Observatory technician.

On March 20 the Northern Hemisphere had its first full day of spring. But for researchers and staff at NOAA’s South Pole Observatory, that day brought austral autumn, and along with it the last appearance of the sun at the South Pole for 6 months.

South Pole station staff experience just 1 sunrise and 1 sunset per year.

It’s a sign!

The signboard pictured here marked the entrance to NOAA’s Research Flight Facility, which was founded in 1961.

Through moves and name changes of NOAA’s research aircraft program, this sign has been a constant physical reminder of NOAA’s dedication to hurricane research.

Learn more about this enduring symbol, the history of NOAA’s severe weather research, and the specialized planes that make it possible — like the NOAA DC-6 weather research aircraft pictured here.

Ever wonder what lurks beneath the surface? One million species live in the sea—but we’ve only discovered about one-third of them because they live in deep, dark parts of the ocean that are hard to explore.

Which ceatures live where the sun doesn't reach? What do they eat? How do we research them? The answers may surprise you!
