El Niño Conditions Now Official; Cold, Snow Take a Parting Swipe at East

By: Bob Henson, 16:55 GMT le 06 Mars 2015

More than a year after the prospect of a 2014–15 El Niño event first surfaced, NOAA’s Climate Prediction Center (CPC) issued a long-awaited El Niño Advisory on Thursday. We’re still a long way from a textbook example of El Niño: ocean warming is barely above the standard threshold, and the atmospheric response is not yet fully formed and consistent. One thing we do know is that sea-surface temperatures in the crucial Niño3.4 region of the eastern tropical ...

The 1969 Hurricane Camille Hurricane Party: It Never Happened

By: Jeff Masters, 13:08 GMT le 04 Mars 2015

On the night of August 17, 1969, Hurricane Camille roared towards the Mississippi coast with sustained winds of an incredible 175 mph. Residents all along the coast fled the wrath of this mighty Category 5 hurricane, but a few unfortunate holdouts chose to ride the storm out rather than evacuate. Legend has it that many of the 23 residents of the infamous Richelieu Manor Apartments in Pass Christian who chose to stay held a hurricane party, in defiance of the hurric...

We won’t have the full state-by-state picture of February’s U.S. climate for a few days, but the outlines are abundantly clear from city climate summaries issued on Sunday. It’s been almost 40 years since the nation has seen a month so starkly divided between a cold east and warm west. The statistics bring to mind early 1977, when snowflakes fell for the first and only time on Miami Beach’s art deco buildings while skiers in the Rockies found themselves hunt...

By: Bob Henson, 18:25 GMT le 27 février 2015

Californians are watching anxiously to see if a “Miracle March” or “Awesome April” salvages the worst snowpack season on record thus far in parts of the Sierra Nevada. Snow that piles up across the mountain range from autumn through spring furnishes more than 60% of the state’s water for consumer and agricultural use. Winter precipitation across California hasn’t been too far from average, but even more than usual, most of it has fallen in a relatively s...

Memorable Snowfall Hits Deep South, Skirts Big Cities

By: Bob Henson, 18:48 GMT le 26 février 2015

A quick-moving snowstorm zipped from northeast Texas to southern Virginia in little more than 24 hours, leaving some parts of the Deep South with more snow than they’ve seen in decades. Rather than carving a deep trough in the eastern U.S., the upper-level energy that generated the snow tracked along the base of a broad pre-existing trough. This channeling of energy helped lead to a storm that had a vast extent from southwest to northeast but a narrow north-south ...
