Tropical moisture is producing heavy rain across the Gulf Coast and lower Mississippi and Tennessee Valleys. Severe storms, seen bubbling up over Louisiana in this GOES East view from June 6, 2019, at 8:50 a.m. ET prompted several tornado warnings in the southeastern region of the state. The storm system had already unloaded 4-8 inches of rain on south central Louisiana by 10 a.m. ET, according to the National Weather Service (NWS).
GOES East captured this view of the severe weather outbreak across parts of Missouri and Oklahoma on May 22, 2019, at 10 p.m. CDT as the storms were beginning to ramp up.
Much of Louisiana and eastern Texas are at risk for flash flooding as several rounds of thunderstorms, seen here by GOES East at 10 a.m. ET on May 9, 2019, bring more heavy rain to the already waterlogged region. Rainfall amounts of 5 to 10 inches are possible “from southeast Texas into portions of Arkansas, Louisiana and Mississippi through the weekend with locally higher amounts approaching a foot,” according to the National Weather Service.
An atmospheric river has drenched California with heavy rain and mountain snow this week, triggering flash floods, mudslides, and winter storm warnings in the Sierra Nevada. The conveyor belt of clouds and moisture stretching across the Pacific easily stands out in this Feb. 14, 2019 image from NOAA's newly operational GOES West (GOES-17) satellite.
Clouds in the sky are constantly in motion, allowing them to take on all kinds of interesting shapes. In the spirit of Valentine's Day, we're sharing a heart-shaped cloud pattern seen from NOAA's GOES East satellite during a powerful nor'easter that barreled up the U.S. East Coast on March 13, 2018.
Clouds blanket much of the central and eastern United States as a sprawling winter storm moves across the country. This image, seen by NOAA's GOES East satellite on Feb. 6, 2019 (10 a.m. ET), shows the developing storm system that is bringing a mix of rain, snow and ice to many states east of the Rockies.
The winter solstice, the official start of astronomical winter, arrives at 5:23 p.m. Eastern Time on December 21. At this exact moment, Earth's Northern Hemisphere reaches its greatest possible tilt away from the sun, and the sun's strongest rays shine on the Tropic of Capricorn (23.5°S latitude). For the 90 percent of Earth's population that lives north of the equator, the December solstice is the shortest day and longest night of the year.
December is the beginning of summer in Earth's Southern Hemisphere. The long days and abundant sunlight help millions of tiny plant-like organisms, called phytoplankton, grow in nutrient-rich coastal waters.
