Damaging, disruptive storms to target NYC, Philly and DC
Storm clouds move in behind One World Trade Center and the Manhattan skyline in New York City on Thursday. Photo by John Angelillo/UPI | License Photo The same setup that brought close to 300 wind damage incidents and a dozen reports of tornadoes in the Midwest on Wednesday will focus on the Atlantic Seaboard from Quebec to the Carolinas into Thursday night, AccuWeather meteorologists warn. High humidity levels combined with a ripple in the jet stream will unleash one or more lines of thunderstorms that will progress from the Appalachians and Piedmont areas toward the Atlantic coast from Thursday afternoon to Thursday night. "As the storms approach the airports at the major metro areas from New York City to Philadelphia and Washington, D.C., airline delays and ground stops will increase dramatically. Some flights may even be cancelled," AccuWeather Chief Meteorologist Jonathan Porter stated. "Such delays and cancellations at these major airports have a tendency to spread quickly elsewhere in the United States air system because planes and crews are not where they need to be based on the existing schedule, resulting in cascading delays and cancellations." Motorists should be prepared for high water and sudden poor visibility as the storms approach. Roads that tend to flood during downpours should be avoided. Powerful wind gusts in many of the storms will average 60-70 mph. Due to the saturated ground in some areas, strong wind gusts during storms can easily push over trees or break off rotting limbs, leading to power outages. There will be an elevated risk of tornadoes in an area from upstate New York and northwestern New England to parts of central and eastern Quebec. This includes the major Canadian metro areas of Quebec City and Montreal, as well as Burlington, Vermont Albany, New York Pittsfield, Massachusetts and Lebanon, New Hampshire in the northeastern United States. A small number of the storms can also bring pea- to marble-sized hail, which, when combined with strong winds and torrential downpours, can damage crops in fields, plants in backyard gardens and other vegetation. As the storms creep along, flash flooding along small streams and urban areas can occur. Two or three storms may blast some locations into Thursday evening. Storms in the metro areas of Richmond and Norfolk, Virginia, as well as Charlotte and Raleigh, North Carolina, may be somewhat more widely separated but can still be severe in some neighborhoods and lead to damage and travel disruptions into Thursday evening. Some thunderstorms and severe weather are also anticipated from South Carolina to Georgia, Florida and Alabama. However, a few storms in these areas can still pack a punch at the local level with brief wind gusts, torrential rain and a sudden cluster of lightning strikes. As a massive dome of heat builds from this weekend to next week, rounds of severe thunderstorms will erupt on the northern edge from the Midwest to parts of the Northeast.

Kantar Study Confirms AccuWeather Provided the Most Accurate Hurricane Forecasts in 2024 with the Most Advance Notice
'This historic report marks the first time a third-party has verified that another source has been more accurate and more effective in predicting hurricanes and their impacts than NOAA's National Hurricane Center' -- AccuWeather Founder and Executive Chairman Dr. Joel N. Myers. STATE COLLEGE, Pa., May 21, 2025 /PRNewswire/ -- A new study conducted by Kantar, one of the world's leading marketing data and analytics companies, has found that AccuWeather provided the most accurate and most effective hurricane forecasts during the 2024 Atlantic hurricane season, outperforming the National Hurricane Center (NHC) and all other known sources. "We are very gratified by these results, which further support our mission of saving lives and protecting property," said AccuWeather Founder and Executive Chairman Dr. Joel N. Myers. "This historic report marks the first time a third-party has verified that another source has been more accurate and more effective in predicting hurricanes and their impacts than NOAA's National Hurricane Center." Key Findings: In 2024, AccuWeather hurricane forecasts consistently outperformed those from the NHC and other sources, with storm track predictions averaging 6.2% greater accuracy overall and 8.9% for U.S. landfalling storms. Landfall location forecasts were 8.6% more accurate on average, while landfall intensity forecasts showed a substantial 37.8% improvement. These forecasts were issued an average of 19 hours earlier and extended 25 hours farther into the future—rising to 31 hours in advance on average for U.S. landfalls. Additionally, maximum wind intensity forecasts were on average 4.0% more accurate overall and 4.4% more accurate for storms hitting the U.S. This Superior Accuracy™ and detail of AccuWeather's hurricane forecasts means people have extra time to prepare and take protective action with greater understanding of the severe weather threats. For example, people and businesses who receive warnings further in advance have an increased window to seek shelter, evacuate or secure property. Clearer communication of the nature, severity, timing and location of the threat explained in a way that is easy to understand and act on leads to improved outcomes, such as lives saved, injuries reduced and property damage minimized due to better-informed decision-making. For businesses, more advance notice and better communication translates to better safety for employees and customers, minimized reputational harm and liability, maximized efficiencies, reduced costs and possibly even increased profits. "As we enter into the 2025 hurricane season, this analysis by Kantar confirms what the emergency managers, businesses, government agencies and millions of individuals who use the AccuWeather Hurricane Service already know: AccuWeather is the gold standard for the most accurate and actionable hurricane forecasting to keep people better prepared and safer," said AccuWeather Chief Meteorologist Jonathan Porter. Porter said the important foundational work of the National Hurricane Center should in no way be disregarded. "The agency provides a vital life-saving service. Our work complements this effort and state and local agencies and companies that need the most accurate forecast of hurricane tracks and impacts ranging from storm surge to rain flooding to tornadoes to wind and water damage, we are not discouraging the use of the National Hurricane Center and the National Weather Service forecasts, but if you want the best and access to expert consulting meteorologists that you can speak to at any time 24/7, AccuWeather is the answer." AccuWeather CEO Steven R. Smith said, "AccuWeather's unique blend of advanced AI and machine learning with six decades of human expertise is key to successfully delivering and communicating risk-based forecasts focused on real-world impact to help people and businesses make the best weather-impacted decisions often with more advance notice than any other source enabling people to be better prepared and stay safer." Storm-Specific Highlights: Hurricane Beryl – AccuWeather accurately predicted Texas landfall 30 hours before the NHC and was the first to forecast severe rainfall and flooding. Hurricane Francine – AccuWeather was the only known source to correctly and consistently forecast landfall as a Category 2 hurricane on the Saffir-Simpson wind scale. Hurricane Helene – AccuWeather was the only known source to accurately predict that Helene "could cause a flooding disaster" and be "a once-in-a-generation storm" for parts of the southern Appalachians. Hurricane Milton -- AccuWeather was the first known source to predict that Milton "could bring damaging winds and flooding to Florida, including areas recovering from Helene." In addition, AccuWeather was the first known source to say, "rapid intensification is possible." Unnamed September Storm – AccuWeather was first to warn of significant impact, issuing its first forecast track 26 hours before NHC and all other known sources. The storm was never named by the NHC. "This is the latest in a long history of examples of AccuWeather's Superior Accuracy™, and we are proud of AccuWeather's track record forecasting severe weather as well as helping people to make the best decisions every day," added Porter. "Our expert meteorologists are poised and ready for the upcoming hurricane season right around the corner." Hurricane season officially begins June 1 and continues through Nov. 30.

Scientists make concerning discovery that could drastically change hurricane season outlook: 'Steroids for weather'
With the Atlantic hurricane season approaching, scientists are closely monitoring ocean temperature changes, attempting to determine what impact they might have on the number and severity of dangerous storms in the months ahead. In late April, the Washington Post reported that a key patch of the Pacific Ocean, west of Peru and Ecuador, had cooled in recent weeks. This came after a stretch earlier in the year when it unexpectedly warmed by several degrees. The cooling came as the Atlantic hurricane season is anticipated to begin in June, and it could increase the chance of a La Niña pattern, which typically brings with it more hurricanes. At the same time, the Atlantic Ocean has also become cooler, which usually means a less-active hurricane season. As noted in the Post, these two cooling events could essentially cancel each other out, resulting in a normal hurricane season. But more changes to either ocean could drastically change the storm outlook for this summer and fall. These changes are tracked by thousands of autonomous floats in the ocean, complemented by ship reports and satellites that measure sea-surface temperature. The Post explained that this is "why we know sea temperatures are cooling in a desolate part of the eastern Pacific Ocean." The U.S. National Oceanic and Atmospheric Administration's Global Ocean Monitoring and Observing Program says that "global ocean thermometers have generated billions of measurements in recent decades" and that they've been "integral" to efforts to interpret the ocean dynamics that still challenge scientific understanding. Changing ocean temperatures and an increased threat of hurricanes are some of the many byproducts of human-caused pollution. As toxic gases continue to be released into the atmosphere, blanketing Earth, they trap more heat on our planet. Relatedly, the 10 warmest years on record have all happened in the last decade. As the planet warms, the weather is becoming more volatile and less predictable. This is causing extreme weather events to occur more frequently and with more severity. Experts have actually referred to Earth's rising temperatures as "steroids for weather." With hurricanes specifically, data from the Center for Climate and Energy Solutions has shown that, although the overall number of storms has stayed relatively steady in recent decades, the intensity of the storms has increased, with major hurricanes happening more frequently. Should we be harnessing the ocean to power our homes? Absolutely Leave it be It depends I'm not sure Click your choice to see results and speak your mind. This phenomenon has experts worried about future hurricane seasons. AccuWeather chief meteorologist Jonathan Porter has warned that this year's season could be similar to that of 2024, which saw five major hurricanes and was "One of the deadliest and most costly hurricane seasons ever seen in the Atlantic," according to National Public Radio. The impacts of Atlantic hurricane seasons typically affect Caribbean islands, Central America, the Gulf of Mexico, and the eastern U.S. No one individual can stop a hurricane, but everyone can be prepared. Keeping a well-stocked survival kit, with supplies like clean water, non-perishable food, and a first-aid kit, can be essential in case disaster strikes. Similarly, it's important to know what not to do during and after a hurricane, including trying to drive through water on flooded roadways. Installing solar panels along with a battery system can also prepare your home, providing access to power even in the case of an extended grid outage. EnergySage's free tools allow you to compare quotes from local, verified installers, and could save you thousands on installation. Homeowners can continue to save, during and outside of hurricane season, as monthly energy bills can plummet with the use of solar power year-round. Something else that's important year-round is the monitoring that NOAA points to the need for. Supporting pro-environment policies that drive these efforts while coordinating with friends, family, and neighbors to reduce the amount of heat-trapping pollution released into the atmosphere — with activities like ride-sharing and community solar programs — can also help to make a difference.
