As 2017 came to a close, GOES-16, the first in the new generation of NOAA geostationary satellites, became operational. This January 5, 2018 view is of the "bomb" cyclone which formed off the US east coast. Intense cold air collided with warmer moist air over the western Atlantic to create this monster cyclonic circulation. [Image links to RAMMB/CIRA animation from their experimental SLIDER animator.]

Heavy winter precipitation in the midwest brought rising waters to the Mississippi River in late February, 2018. Last opened just two years ago, the Bonnet Carre Spillway, located in the southwestern corner of Lake Pontchartrain, was opened on March 8th, to relieve pressure on the levees. Engineers sought to keep the river stage at New Orleans below 17 feet, and have opened about half of the 350 bays. This gallery of images will catalog the macro-scale movement of this sediment-laden water. More images can be found in the recent images in the Image of the Week collection.
