Rely on official NHC forecasts at hurricanes.gov and information from trusted media partners. Be cautious of sensational headlines and instead look for reliable sources to determine a storm's potential impacts. More tips in the video below: youtube.com/watch?v=ZV3R5e…

Flood alerts are in effect for nearly 14 million Americans as severe weather stretches across the South from New Mexico to Louisiana. Meteorologist @RobMarciano is tracking the storms.

For the sixth straight day, violent weather is threatening millions in the central part of the country. Meteorologist @RobMarciano is tracking the storms.

Heavy winter snow and recent record rainfall have caused the Cheboygan River in Michigan to rise, flooding lakeside neighborhoods with massive chunks of ice and prompting a state of emergency. Meteorologist @RobMarciano reports on the impact.

Another possible outbreak of tornadoes, hail and gusty winds is threatening millions of Americans. Meteorologist @RobMarciano is tracking severe weather.

Rough overnight Great Lakes thru Great Plains: 7 tornadoes Winds over 80 mph Hail to softball size In all nearly 200 damaging storm reports

Getting big support from @GayleKing @CBSMornings and my @CBSNews fam for #TheNextBigThing thank you so much!!

Look at this astronaut's face during reentry, knowing the capsule exterior is at 5,000°F. The physics of why he's alive are wild. The air in front of the capsule compresses so violently at Mach 25 that it turns into plasma. 5,000°F on the surface. Half the temperature of the sun. The heat shield absorbs that energy by literally burning itself away, layer by layer, carrying the heat with it as gas. One inch of material is the entire margin. On the outside of that inch: 5,000°F. On the inside: 75°F. Room temperature. The thermal gradient across that single inch is the steepest temperature drop humans have ever engineered. The orange glow in the window is ionized nitrogen and oxygen. That plasma is why comms go black for six minutes during reentry. Ground control can't reach the crew. The astronauts are alone inside a fireball, falling at 25,000 mph, watching the laws of thermodynamics keep them alive through a 1-inch wall. Artemis II did exactly this last night. Four astronauts hit Earth's atmosphere at 24,664 mph, rode a 4,900°F plasma sheath for six minutes of radio silence, and splashed down a mile from target. The heat shield is now being inspected for cracks. They found over 100 on the last unmanned test.

@aaronjayjack Great shot Aaron!!! Can we use this on CBS and across our platforms??
