Tropical Depression Brings Early Start to 2017 Hurricane Season

Hurricane season is off to an early start this year with Tropical Depression 1 churning out over the Atlantic Ocean more than a month before the official start of the season. But while it’s an early bird, the storm won’t impact land and is expected to dissipate by Friday. It’s not unheard of to see storms form early, as the official season is a

Here’s Your Early Hurricane Season Preview

Spring is in full bloom in the U.S., which means summer isn’t far behind. And with this march of the seasons, the risk for hurricanes returns. Inevitably, there is a desire to know how active the season is going to be as far in advance as possible. This season looks to be just slightly less active than average, which translates to a slightly

Could Another El Niño Be Brewing? Only Time Will Tell

Just over a year ago, the Earth was coming off of one of the strongest El Niños on record. Waters in the eastern Pacific warmed by El Niño began to cool toward normal in summer and even edged in the opposite direction — as sometimes happens — toward a La Niña. That cooling reached modest levels through the fall, registering as a weak La Niña. Now

Fewer Freezing Nights

The growing season is underway in parts of the U.S., primarily in the Southeast. As the world warms, the average date of that last spring freeze is occurring earlier in the year, extending that season. While the longer growing season does have some benefits, it also raises concerns about both agriculture and health. Consistently warmer weather help

Cowbell fire in Florida

The Climate Context for Raleigh’s Rains and Florida’s Fires

Two opposing weather situations are playing out right now in the Southeast: While parts of North Carolina are submerged thanks to a record downpour, Florida is battling wildfires fueled by a drought that now outranks the one in California. While these conditions sit at opposite ends of the weather seesaw, both may be affected by a changing climate.

The World’s Ice Is Disappearing. This Winter Was a Prime Example

Last month, the National Snow and Ice Data Center announced that sea ice in both the Arctic and Antarctic Circles had reached a new low. In the Antarctic, where the summer season just wrapped up, rapid ice melt led to the lowest sea ice minimum ever recorded for the area. At the same time, on the other side of the world, the Arctic Ocean was

New Lightning ‘Eye in the Sky’ Could Improve Storm Forecasts

Lightning strikes the ground around the U.S. roughly 25 million times a year, but that’s nothing compared to the number of lightning flashes that stay up in the cloud, which happen five to 10 times as often. Now, there is a new eye in the sky watching out for all lightning types, which could improve forecasting of the severe storms that lightning

Western Snowpack Up, But Less Likely in the Future

The start of April marks the end of the winter wet season in the western U.S., the time of year when the region gets most of its precipitation. Measuring the snowpack at this time indicates how much water will melt from the snowpack during the hot and dry summer months that follow, making it a critical resource for agricultural, residential

This is Where the Wind Blows in the U.S.

We’ve reached the end of the windiest month of the year. But in other months, wind will continue to play an increasingly large role in the U.S. power mix. At the end of last year, wind capacity surpassed hydroelectric capacity for the first time in the U.S. Over the past decade, wind power has exploded in the U.S. Over that time, generating

Tropical Cyclone Debbie Pounds Queensland with Powerful Storm Surge

Tropical Cyclone Debbie made landfall along the Queensland coast Tuesday as a Category 4 cyclone on the Australian cyclone wind scale. Debbie produced maximum sustained winds of around 110 mph, which would place it at the threshold of a Category 3 hurricane in the Atlantic.
