Atmospheric River Is Behind Heavy Rains Inundating California
Europe is sweltering under a heat wave, California is being inundated with rain, and a polar vortex is headed for Canada. So what exactly is going on with the weather these days?
Michele Power, a meteorologist for News12, said that one explanation for this "parade of storms," at least in the United States, is a phenomenon called the "atmospheric river," which is a narrow band of concentrated moisture in the atmosphere that often brings with it heavy amounts of rain.
While atmospheric rivers are fairly normal weather events, this recent bout has been especially intense. Over the past couple of weeks, the extra moisture has given California its largest-ever mid-January snowpack and a foot-and-a-half of rain, contributing to widespread flooding. "Ski resorts are rejoicing, but certainly for those of us who live there that is a huge issue," Power said.
The upside of all this — for California at least — is drought relief. The previously parched state now has more water than it can handle, and this does make up for some of the recent lack.
Power said the next week is expected to be quieter, but the pattern could return this season.
"This is not going away, but it's starting to ease," she said.
Looking at the issue on a more global scale, the meteorologist said you have to talk about the "elephant in the room" — climate change.
"That increase in temperature is actually helping increase the amount of rain that is falling," she said. "We can't attribute every single storm that does happen to climate change… but climate change and the warmer atmosphere is actually helping enhance these storms."
Heavy rainfall flooded parts of Massachusetts and Rhode Island, with two communities declaring a state of emergency as water poured into homes, creating moats around their foundations and leading to boat rescues of residents. Concern about a dam listed in poor condition led to more evacuations.
The leading decongestant used by millions of Americans looking for relief from a stuffy nose is no better than a dummy pill, according to government experts who reviewed the latest research on the long-questioned drug ingredient.
Hurricane Lee, still a Category 3 storm with winds of 115 mph, is expected to increase in size but be significantly weaker in the coming days, as it turns north to reach the U.S. East Coast, according to the National Hurricane Center.
The U.S. approved updated COVID-19 vaccines Monday, hoping to rev up protection against the latest coronavirus strains and blunt any surge this fall and winter.
An earthquake has sown destruction and devastation in Morocco, where death and injury counts continue to rise as rescue crews dig out people both alive and dead in villages that were reduced to rubble.
Hurricane Lee whipped up waves of more than 15 feet (5 meters) on Monday as the Category 3 storm cranked through open waters just north of the Caribbean region.
