Hail threatens to damage Helene-ravaged North Carolina ahead of flash flood risk

Hail threatens to damage Helene-ravaged North Carolina ahead of flash flood risk

New York Post08-05-2025
The weather pattern that soaked parts of Texas and Louisiana earlier this week will shift to the east before stalling, setting up days of severe weather and a prolonged flash flood threat through early next week.
According to the FOX Forecast Center, a broad area across the South and mid-Atlantic will face an increasing threat of thunderstorms beginning Thursday afternoon when a cluster of storms will develop across Middle Tennessee and move east into northern Alabama, North Georgia, and western North Carolina, an area that is still recovering from Hurricane Helene.
Storms will track along a stalled cold front through the weekend with a widespread 3-5 inches of rain expected from Florida through the Carolinas, with some tallies reaching a foot and possibly more.

Thursday's severe storms will develop in the afternoon and could produce very large hail, greater than 2 inches, and severe wind gusts in an area covering cities like Knoxville, Tennessee, and Asheville, North Carolina, where many communities are still recovering from Helene's devastation last September.
There is also a tornado threat associated with these storms. NOAA's Storm Prediction Center has issued a Level 2 out of 5 risk for severe thunderstorms for the region.

Flash flood threat for Southeast lasts through the weekend
The worst of this week's flooding appears to have impacted parts of southern Louisiana, where some communities reported over 8 inches of rainfall in just 24 hours.
'You had training storms just dumping buckets of rain over the same spots, which is why we're seeing a lot of clustering near Lake Charles, Louisiana, in between I-10 and I-49,' FOX Weather Meteorologist Haley Meier said while pointing out storm reports.
A rather unusual weather pattern for May, known as an Omega block, is largely responsible for the stagnant system, with prolonged periods of warmth in some areas of the country and steady rain in others.

The National Weather Service in New Orleans warns that the aftermath of the rain days later can be just as consequential, with many streams and rivers across the lower Mississippi Valley at moderate flood stage and likely facing weeks of high water levels.
How much more rain is expected?
Computer model forecasts show a widespread swath of 2-5 inches of rainfall over the next five days, with some communities possibly seeing totals upwards of a foot into next week.

Cities such as Tallahassee, Florida; Savannah, Georgia; and Charleston, South Carolina, are all in the zone of potentially the heaviest precipitation, where rainfall totals could approach double-digits before the wet weather pattern winds down.
'A good 2 to 3 inches for a spot like Panama City, Florida, and, for Gulfport, Mississippi, 1 to 2 inches. But I do think if we have a couple storms that park overhead and can produce some pretty intense rain rates, which is what's projected, these numbers may be under-doing it just a touch,' Meier said.
While the flash flood threat is elevated through the week and into the weekend, it is not currently near the top of the threat scale, thanks in part to many areas along the Eastern Seaboard being in drought conditions and in need of rainfall.

In addition to any storm potentially becoming strong to severe, with hail and damaging winds, it's the rainfall and associated flooding that have forecasters most concerned.
Flash flooding is the deadliest weather-related hazard in the U.S., and, according to NOAA data, an average of 127 people die from it each year.
According to National Weather Service forecasters, just 6 inches of fast-moving water can knock an adult off their feet, and a foot of floodwater can carry a car away.

Northern Lights Update: These 14 States Could See Aurora Borealis Saturday

This weekend will bring several U.S. states a chance at seeing the northern lights, according to a forecast from the National Oceanic and Atmospheric Administration, which is anticipating some of the highest auroral activity in recent weeks on Saturday. Aurora Borealis in the United Kingdom. (Photo by) Getty Images NOAA has issued a Kp index of five for Saturday, a designation that calls for a 'moderate aurora' that 'can be quite pleasing to look at' for viewers in the right areas. The curved viewing line for Saturday nearly touches the border between South Dakota and Nebraska, as chances of seeing the northern lights increase the farther north people are of the line. Friday's northern lights forecast is not nearly as strong as Saturday's, with NOAA issuing a Kp index of two and a viewing line at the U.S.-Canada border.

Saturday's viewing line includes states and areas like Alaska, Washington, northern Idaho, Montana, northern Wyoming, North Dakota, South Dakota, Minnesota, the northern edge of Iowa, Michigan, the northern edges of New York, Vermont, New Hampshire and Maine. Saturday's viewing line. NOAA Between the hours of 10 p.m. and 2 a.m. is generally considered the best window of time to catch a view of the northern lights. To increase your chances at seeing aurora borealis, try viewing from areas with little to no light pollution and clear skies. Vantage points can also increase chances of seeing the lights. What's The Best Way To Photograph The Northern Lights? Smartphone users should use night mode and avoid using flash if they want to photograph the northern lights, while people with traditional cameras should use low apertures while shooting. Wide-angle lenses and tripods can also help capture good images. Key Background The northern lights have been active in the U.S. for over a year now, benefiting from the peak of the sun's 11-year solar cycle, which generates coronal mass ejections and solar flares that contribute to higher auroral activity. NASA forecasts say the lights will remain active into next year and eventually decrease in strength as the solar cycle moves forward.

Map Shows Where 100-Year Floods Have Hit Across the US Over Past Year

Based on facts, either observed and verified firsthand by the reporter, or reported and verified from knowledgeable sources. Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content. The term "100-year flood" implies that the event is a rare occurrence; however, dozens of such storms have inundated the United States over the past year alone, prompting concern that they are occurring more frequently as the Earth's climate continues to warm. Why It Matters Flooding is the second-deadliest weather hazard in the U.S., next to extreme heat. Devastating flood events have made headlines numerous times this year, including a 1,000-year atmospheric river event that hit the Midwest and South in April and the deadly floods that inundated Central Texas over the July 4th weekend. The frequency of such flooding rainstorms, which often go hand-in-hand with death and destruction, is alarming. What's even more concerning is that AccuWeather meteorologist Alex DaSilva told Newsweek that these events are happening more frequently. What To Know In 2024, dozens of 100-year rainstorms struck the U.S. Each point is marked on the map below, created by Colorado State University. The points marking each event are widespread, with only a few states escaping unscathed. Last year wasn't a one-time occurrence, either. This year is also "shaping up to be one of the most flood-impacted summers on record in the United States," AccuWeather reported. A map from Colorado State University shows where 100-year rainstorm events were documented in 2024. A map from Colorado State University shows where 100-year rainstorm events were documented in 2024. Colorado State University What Is a 100-Year Flood? The United States Geological Service (USGS) describes the term "100-year flood" as an attempt "to simplify the definition of a flood that statistically has a 1-percent chance of occurring in any given year." Where Did 100-Year Rainstorms Hit in 2024? On the CSU map, countless points pepper the Eastern Seaboard around North Carolina and South Carolina after Hurricane Helene struck in September. Others show the devastating impact of the summer monsoon season in New Mexico, which caused deserts to flood and cars to become stranded as water washed over a highway. Vermont faced catastrophic floods in late July. Central Texas, known as Flash Flood Alley, experienced several 100-year rainstorms last year, as did Florida, with a scattershot of points dated as occurring during the Atlantic hurricane season. There was also an onslaught of precipitation that hit South Dakota in June 2024, as well as a similar storm that measured as a 100-year event at several locations in Missouri in November, among others. Only a few states emerged unscathed, including Iowa, Wisconsin, Oregon, Washington, and Massachusetts, but most of the U.S. experienced some form of severe flooding precipitation last year. Why Are 100-Year Floods Occurring More Frequently? The map's creator, Russ Schumacher, a professor of atmospheric sciences at CSU and a CSU climatologist, told Newsweek that improved technology, such as radar, provides better access to data, which can make it seem as if the flood events are happening more frequently. However, he also stressed the impact of climate change. "The physics of climate change tells us that we should see these extreme events more frequently," he said. As the atmosphere grows warmer through global warming, its ability to hold moisture increases, DaSilva told Newsweek. "This is why in the wintertime, we typically don't see too much flash flooding in the wintertime," DaSilva said. "It's too cold, and there's snow, of course, but it's hard to get the moisture content you need for heavy rain events in the wintertime because it's cooler out. In the summertime obviously the temperature is above freezing, but the atmosphere can hold more water content. There's more moisture to squeeze out." Which States Have Increased Flood Risk? As the atmosphere's ability to hold moisture increases, DaSilva told Newsweek that states in the Ohio and Tennessee valleys are becoming wetter, while areas like California are becoming drier. What People Are Saying AccuWeather meteorologist Alex DaSilva told Newsweek: "When the atmosphere is getting warmer as a what it's doing is making summer warmer and the shoulder seasons warmer as well. What's happening is those seasons, especially in the summertime, the [atmosphere's] ability to hold more moisture is going up as well." DaSilva added: "It doesn't guarantee we will see more rain over a certain area, it rains, it's going to rain heavier." The USGS in a webpage about 100-year flood events: "In other words, over the course of 1 million years, these events would be expected to occur 10,000 times. But, just because it rained 10 inches in one day last year doesn't mean it can't rain 10 inches in one day again this year." What Happens Next As the probability of heavy rain events increases, people are advised to have a flood plan in place before such an event occurs in their area. People should also never drive on a flooded roadway, as most flood-related deaths occur in vehicles.

Upgraded Northern Lights Alert: 14 States May See Aurora This Weekend

The aurora borealis or northern lights in the night sky over Shiprock, New Mexico. Days after the Northern Lights were glimpsed from northern U.S states — including Idaho, New Hampshire, Michigan and even Massachusetts — displays may be visible once again on Saturday night (July 26-27), according to a forecast by the National Oceanic and Atmospheric Administration's Space Weather Prediction Center. Although astronomical darkness is in short supply at northerly latitudes, sky-watchers in 14 U.S. states may have a chance to see the aurora borealis on the northern horizon during the night into Sunday morning. Northern Lights Tonight: Latest Forecast The agency's new three-day forecast indicates a minor geomagnetic storm, measured at a value of up to G1 on a scale of G1 to G5. According to NOAA's forecast, the Kp index — which provides a rough guide to the intensity of aurora displays — may reach 5 around 09:00-12:00 UTC (4:00 a.m. through 7:00 a.m. EDT). However, there is also a possibility that the geomagnetic storm could be a stronger G2 event. In a discussion post, NOAA officials stated that a G1 (Minor) geomagnetic storm is likely on July 27 'with a chance for isolated G2 (Moderate) periods due to CME effects from an event that left the Sun on 23 July.' According to the cause is a coronal mass ejection — a clump of charged particles ejected by the sun on July 23 — which is expected to interact with Earth's atmosphere. NASA's WSA-Enlil model has the CME striking Earth. Northern Lights Tonight: Where Aurora May Be Visible Keep an eye on NOAA's latest aurora viewline for an indication of exactly where aurora displays will potentially be seen from, but it will likely include parts of 14 northern U.S. states, and Canada, on July 26/27. U.S. states that may see aurora include (northerly parts of) Washington, northern Idaho, Montana, Wyoming, North Dakota, South Dakota, Minnesota, Wisconsin, Michigan, Iowa, New York, Vermont, New Hampshire and Maine. Areas far from light pollution are likely to offer the best views. Check NOAA's 30-minute forecast or use the Glendale App for the latest forecasts and real-time information on substorms. Northern Lights Tonight: Why Aurora Are Being Seen So Far South The aurora borealis is being seen at more southerly latitudes than usual due to an increase in solar activity. Magnetic activity on the sun is currently at a 23-year high because it's reached solar maximum — the height of our star's 11-year solar cycle. Having possibly peaked in late 2024, the sun may now be quietening down, but solar maximum periods often have double peaks. It's also known that some of the best aurora displays can happen in the two years post-solar maximum. Decent aurora sightings in the U.S. are thus expected through 2026 and 2027. Northern Lights Tonight: Best Places And Times To See The Aurora The best places to see the Northern Lights are those at about 65 degrees north latitude between September and March (when there is sufficient hours of darkness). This is where the auroral oval sits, making northern Norway, northern Sweden, northern Finland, Iceland, Alaska and northern Canada reliable places for aurora sightings when skies are clear. Northern Lights Tonight: Aurora Explained The Northern Lights are caused by disturbances in Earth's magnetic field created by the solar wind. As charged particles accelerate along the magnetic field lines toward the polar regions, they collide with oxygen and nitrogen atoms, exciting them. That causes a photon of light to be released. Wishing you clear skies and wide eyes.
