2024 has seen several strong storms hit the U.S. West Coast delivering repeated rounds of widespread rains and mountain snow, with Southern California experiencing the heaviest rainfall totals. Total Precipitable Water imagery (MIMIC TPW) conveying data acquired by microwave sensors on polar-orbiting satellites is a key tool for meteorologists tracking atmospheric... Read More
Abundant convection over the southern Pacific Ocean has organized into a tropical cyclone (named Nat) as the system moved to the east of the Samoan Islands. GOES-18 infrared imagery, above, shows the strong convection that developed just east of Olosega; by 0700 UTC on 5 February 2024, very cold cloud tops (brightness temperatures cooler than -90oC)...
