Zombie storms are rising from the dead thanks to climate change – Live Science

Wildfires are burning the West Coast, hurricanes are flooding the Southeast — and some of those storms are rising from the dead. 

“Zombie storms,” which regain strength after initially petering out, are the newest addition to the year 2020. And these undead weather anomalies are becoming more common thanks to climate change.

“Because 2020, we now have Zombie Tropical Storms. Welcome back to the land of the living, Tropical Storm #Paulette,” the National Weather Service wrote on Twitter on Tuesday (Sept. 22).

Earlier this month, Tropical storm Paulette formed in the Atlantic Ocean and made landfall in Bermuda as a Category 1 hurricane, according to CNN. It then strengthened over land into a Category 2 hurricane, before weakening and dying off five and half days later.

But then, Paulette opened her frightening eye once again. She wasn’t gone. 

Paulette regained strength and became a tropical storm once more about 300 miles (480 kilometers) away from the Azores Islands on Monday (Sept. 21), according to CNN. The term “zombie storm” is new, and though the phenomenon has been recorded before, it is thought to be rare. 

But zombie storms are going to happen more often, said Donald Wuebbles, a professor of atmospheric sciences at the University of Illinois at Urbana-Champaign. And as with other natural disasters that have been intensifying in recent years, such as wildfires and hurricanes, climate change and rapid global warming are to blame. 

There has been an “extreme amount of heating of the Gulf (of Mexico), particularly in some of the ocean areas off of the Carribean,” Wuebbles told Live Science. The Gulf of Mexico, where many hurricanes gain strength before hitting the U.S., is particularly vulnerable to global warming because the gulf waters are very shallow — and thus heat up easily, Wuebbles said.

Atlantic Ocean storms typically form in warmer parts of the ocean near Africa, due to a combination of atmospheric and ocean conditions. They then “race across” the ocean toward the Americas, Wuebbles said. Hurricanes need warm water and moist air to form, according to the University Corporation for Atmospheric Research. Storms grow if there’s a continuous supply of energy from warm water and air, and they weaken when they move over cooler waters or over land.

“If they’re not so strong, in the past, they would just die out,” over the Atlantic, Wuebbles said. But now, they reach warm water in the Carribean region and pick up energy again, he added. This is also true for storms that haven’t died out yet. For instance, about a month ago, Hurricane Laura strengthened overnight from a Category 1 storm to a Category 4 storm because it picked up energy from warm water in the Gulf, Wuebbles said. 

With a warming globe, “storms are likely to become more intense,” he added. That means the idea of “zombie storms” may be here to stay. 

Thankfully Paulette seems to have become a post-tropical cyclone once more and will die out soon, according to the National Hurricane Center

Severe storms, flooding and excessive heat make for a messy Memorial Day weekend – CNN

(CNN)Memorial Day weekend is in full swing, but if you’re planning on going outside you might want to pack a poncho or umbrella. It’s going to be a wet one in many areas across the United States.

Rain showers, large hail, strong winds and record temperatures are all part of the forecast.

Northeast

It was a rainy Saturday in cities across the Northeast, including New York, Philadelphia, Providence, Rhode Island and Hartford, Connecticut. Fortunately, that’s about to change.
Sunday and Monday will bring gradual clearing to these cities, with more sunshine and drier conditions. But high temperatures are expected to remain below average through Monday.
Much warmer temperatures are expected Monday for cities like Pittsburgh, Washington D.C., and Syracuse, New York.

Southeast

Rain is the main theme for the Southeast.
Gulf of Mexico moisture will surge into the region, triggering heavy rain and thunderstorms Sunday and Monday. It won’t be an all-day washout for most areas, but plan on showers interrupting your BBQ, hike or pool time.
South Florida may be one of the rainiest places over the next week. Cities like Miami, West Palm Beach, Naples and Ft. Myers have heavy rain and thunderstorms forecast for every day of the week. This could lead to localized flooding.
On Saturday, many cities — including Atlanta, Greenville-Spartanburg, South Carolina, Knoxville and Chattanooga, Tennessee — saw their first day with above average high temperatures in nearly a week. It’s expected to stay above average for all these areas through Monday.

Plains and the Midwest

Severe storms are likely from Texas to Iowa on Sunday. Damaging winds and large hail pose the main threats but isolated tornadoes are also possible. The system that is bringing the severe storms is not expected to move very much over the next 48 hours, so flooding will also be a concern. Widespread rainfall accumulations from Texas to Iowa are expected to range between 3 to 5 inches, with isolated higher amounts.
Some areas of the Midwest will experience their warmest temperatures of the year so far. Monday morning low temperatures are expected to reach record high levels for at least six cities.

West Coast

After dealing with red flag warnings and increased fire weather risks the past few days, areas of Colorado, western Kansas and northern New Mexico will finally get some relief. The chance of rain and slightly cooler temperatures are expected on Sunday and Monday.
The Southwest can expect to heat up. Many cities, including Phoenix, San Francisco, Las Vegas, and Palm Spring, California, are under Excessive Heat Watches next week.
They aren’t alone. Sacramento, Los Angeles, Reno, Nevada and Tucson, Arizona, will also experience temperatures well above average for much of next week.

Severe storms and tornadoes could hit the South again on Sunday, forecasters warn – USA TODAY

CLOSE

One week after the Easter Sunday tornado outbreak, parts of the South will once again be at risk for more dangerous weather.

Accuweather

A week after the deadly and devastating Easter Sunday tornado outbreak, another round of severe weather is forecast for Sunday across portions of the South.

Severe storms are most likely Sunday across the Gulf Coast states, the Storm Prediction Center said. “The greatest threat appears to be from Louisiana to Georgia, with significant severe storms expected including tornadoes and damaging winds. Large hail is likely as well,” the center warned.

Adding to the danger will be the risk that some of the tornadoes could be wrapped in rain or may occur after dark, AccuWeather said.

Cities within the greatest risk area include Baton Rouge, Louisiana; Jackson, Mississippi; and Montgomery and Mobile, Alabama. Big cities like New Orleans, Houston and Atlanta could also see powerful storms.

Drenching rain will accompany the severe weather, especially in portions of central Alabama and central Georgia, where flash flooding is possible, the National Weather Service said. 

However, the overall setup does not look as favorable for as numerous and intense tornadoes as was seen across the South on Easter Sunday and Monday, the Weather Channel said.  

During last week’s outbreak, more than 100 tornadoes struck the South, killing at least 36 people, the National Weather Service said.

Looking ahead, additional rounds of severe weather are anticipated for the South in the coming weeks, AccuWeather said.

“In terms of severe weather and tornado risk, the overall weather pattern is loaded for the rest of April and into May,” Paul Pastelok, AccuWeather’s top long-range forecaster, said.
