NEW ORLEANS – Days of rounds of showers and thunderstorms have soaked parts of Texas and Louisiana, and the FOX Forecast Center warns that the pattern responsible for the heavy rainfall and flooding is not done yet.
As the wet weather pushes eastward, areas across the South and mid-Atlantic face an increasing threat of thunderstorms, which will last through the weekend and into next week.
The worst of the weather appears to have impacted parts of southern Louisiana, where some communities reported over eight 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.
Damage Reported In Louisiana After Possible Tornado Amid Active Week Of Weather Along Gulf Coast
Forecast models 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 two to three inches for a spot like Panama City, Florida, and, for Gulfport, Mississippi, one to two 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 maybe under doing it just a touch," said Meier.
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.

Know Your Flood Terminology: What Flood Watches, Warnings And Emergencies Really Mean
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 United States, and, according to NOAA data, an average of 127 people die from it each year.
According to NWS forecasters, just six inches of fast-moving water can knock an adult off their feet, and a foot of floodwater can carry a car away.

The eight places that are set to avoid 600-mile rain storm
The UK's summer has been a mixed bag of weather, with the unpredictable forecasts set to continue as temperatures are predicted to plummet and rainstorms loom. Weather maps reveal a 600-mile band of rain is poised to batter the UK in less than a fortnight, leaving all but eight counties bracing for wet and chilly conditions. The unsettled weather is due to kick off on 27 August, with predictions indicating that the East Midlands and southern Scotland will bear the brunt of the heaviest downpours. READ MORE: Mum left with just £1 after phone call cost her £10,500 READ MORE: DVLA driving licence change takes effect in August affecting thousands of drivers According to WXCharts weather maps, Aberdeenshire, Somerset, Middlesex, Kent, Essex, Suffolk, Norfolk and Cambridgeshire are the only areas likely to escape the impending rainfall. Currently, the UK is enjoying its fourth heatwave of the summer, with mercury levels reaching up to 30C in some regions. However, the incoming weather front could see temperatures plunge to a chilly 5C in central Scotland and around 10C in parts of England. The rainfall is expected to persist for approximately 24 hours, intensifying to around 3mm per hour in northern England on 28 August, while largely retreating from the south, according to the Express. While the impending rainstorm signifies a shift from the hot and sunny conditions enjoyed by most of the country earlier this month, it's just the latest in a series of fluctuating weather patterns this summer, characterised by scorching highs and disruptive downpours. The Met Office has issued yellow thunderstorm warnings for a large portion of north-eastern Scotland and eastern Northern Ireland on Thursday. With the heatwave conditions persisting, there have been alerts about challenging driving conditions, potential disruptions to power supplies and public transport, as well as a risk of flooding. The weather forecaster's outlook for the rest of the month is similarly marked by potential upheaval, brought on by areas of low pressure advancing from the Atlantic. Its long-range forecast for 19 to 28 August indicates: "This brings an increasing possibility of stronger winds and rain, some of which could be heavy and thundery, especially for southern and western areas, but this perhaps becoming more widespread with time." The Met Office's predictions for the period between 29 August and 12 September also caution of "unsettled conditions with showers or longer spells of rain", with the possibility of "heavy and thundery rain and strong winds". It goes on to mention that temperatures will generally stay above average, but with the likelihood of sporadic hot spells in the south. Earlier this week, the UK experienced yellow heat alerts in seven regions in England, as the country has been grappling with heatwaves throughout the season. The yellow alerts highlight a potential increase in fatalities "particularly among those ages 65 and over or with health conditions", according to the UK Health Security Agency (UKHSA). Upon issuance, the warning indicates potential strain on health services, with internal temperatures in hospitals and care homes possibly surpassing the "recommended threshold for clinical risk assessment", and potential effects on the workforce's capacity to provide services.

Pakistan defends flood response after more than 270 people killed
Rescuers recovered dozens more bodies from the rubble of collapsed homes in a north-western district of Pakistan, bringing the death toll to at least 274, as authorities defended their response to the flooding. Heavy rains and flooding also killed dozens of people in neighbouring Kashmir. Mohammad Suhail, a spokesman for Pakistan's emergency service, said 54 bodies were found in Buner, a mountainous area in Khyber Pakhtunkhwa province, where torrential rains and cloudbursts triggered massive flooding on Friday. Mr Suhail said villagers remained missing, and search efforts were focused on areas where homes were flattened by torrents of water that swept down from the mountains, carrying boulders that smashed into houses like explosions. Authorities have warned of more deluges and possible landslides between now and Tuesday, urging local administrations to remain on alert. Higher-than-normal monsoon rains have lashed the country since June 26 and killed more than 600. In India-administered Kashmir, located across Pakistan's north-eastern border, rains triggered more flash floods in two villages in the Kathua district, killing seven people, officials said on Sunday. Rescuers in Chositi village are still looking for dozens of missing people after the area was hit by flash floods last week during an annual Hindu pilgrimage. At least 60 people were killed, and some 150 injured. More than 300 others were rescued. Residents in Buner have accused officials of failing to warn them to evacuate after torrential rain and cloudbursts triggered deadly flooding and landslides. There was no warning broadcast from mosque loudspeakers, a traditional method in remote areas. The government said that while an early warning system was in place, the sudden downpour in Buner was so intense that the deluge struck before residents could be alerted. Lieutenant General Inam Haider, chairman of the national disaster management authority, told a hastily convened news conference in Islamabad that Pakistan was experiencing shifting weather patterns because of climate change. Since the monsoon season began in June, Pakistan has already received 50% more rainfall than in the same period last year, he said. He warned that more intense weather could follow, with heavy rains forecast to continue this month. Some countries have reached out to Islamabad offering help, but Lt Gen Haider said Pakistan had sufficient resources and did not require foreign assistance at this time. Asfandyar Khan Khattak, director-general of the provincial disaster management authority, said there was 'no forecasting system anywhere in the world' that could predict the exact time and location of a cloudburst, a sudden and intense downpour. Idrees Mahsud, a disaster management official, said Pakistan's early warning system used satellite imagery and meteorological data to send alerts to local authorities. These were shared through the media and community leaders. An emergency services spokesman in Buner, Mohammad Sohail, said more than half the damaged roads in the district had reopened by Sunday, allowing vehicles and heavy machinery to reach cut-off villages. Crews were clearing piles of rocks and mud dumped by the floods. They were still using heavy machinery to remove the rubble of collapsed homes after families reported that some of their relatives were missing. Pakistan is highly vulnerable to climate-induced disasters. In 2022, a record-breaking monsoon killed nearly 1,700 people and destroyed millions of homes. The country also suffers regular flash floods and landslides during the monsoon season, which runs from June to September, particularly in the rugged north-west of the country, where villages are often perched on steep slopes and riverbanks. Experts say climate change is intensifying the frequency and severity of such extreme weather events in South Asia. Khalid Khan, a weather expert, said Pakistan produced less than 1% of planet-warming emissions but faced heat waves, heavy rains, glacial outburst floods and now cloudbursts, underscoring how climate change was devastating communities within hours.

Heat wave returns to Colorado this week with temperatures forecast to reach almost 100 degrees
Sunday is the beginning of another heat wave that will slowly increase temperatures this week across the Denver metro area to nearly 100 degrees. The average high temperature for Denver is 87 degrees and we will be above, until a front moves through for the weekend dropping temperatures to nearly normal. Sunday highs will be in the upper 80s to low 90s for the Front Range, with a mix of upper 70s and low 80s for the mountains. The mountains could see scattered storms Sunday afternoon with just a slight chance for an afternoon storm in the northern Front Range and on the eastern plains. The chance of storms and rain showers increases for the metro area beginning Friday.
