Excessive heat warnings bring elevated wildfire risk, potential for power outages and rising death toll

San Francisco recorded its hottest day of the year on Tuesday, and Phoenix set a record for the hottest 1 October on record, as the National Weather Service predicted record-high fall temperatures across the south-western US.

With temperatures hitting 100F (38C) or higher in many places, officials and local media outlets issued warnings that the heat posed “a significant threat to property or life”. Excessive heat warnings were in place across the region, bringing with it warnings about elevated wildfire risk, the potential for sweeping power outages in California and a rising toll of heat-related deaths, a particularly deadly risk for unhoused people and the elderly.

Chongqing authorities say cloud seeding to break heatwave did not cause winds that sent laundry flying

It was the talk of the town. After authorities sought to break a long-running heatwave in Chongqing by using cloud-seeding missiles to artificially bring rain, the Chinese megacity was blasted by an unusual weather event – an underwear storm.

Termed “the 9/2 Chongqing underwear crisis”, an unexpected windstorm on Monday brought gusts of up to 76mph (122km/h), scattering people’s laundry from balconies on the city’s high-rises. Douyin, China’s sister app to TikTok, was filled with videos of pants and bras flying through the skies, landing in the street and snagging on trees.

Weather tracker: Francine looking likely to be next Atlantic hurricane

An area of low pressure in the Gulf of Mexico is moving landward, and is expected to bring intense rainfall

Francine could soon be the next to be ticked off the list of Atlantic hurricane storm names this week. On Friday, a broad area of low pressure emerged in the Gulf of Mexico, designated as Invest 91L. An “invest” – a shorthand for “investigative area” – refers to a region of atmospheric disturbance, characterised by low pressure and thunderstorms, and is closely monitored for its potential to evolve into a tropical cyclone.

Invest 91L is anticipated to encounter more favourable environmental conditions as it progresses northward over the coming days, meandering along the eastern coasts of Mexico and Texas. The National Hurricane Center has now labelled this as a potential tropical cyclone, and it is expected to reach hurricane status before reaching the Gulf coast of the US. It advises that hurricane and storm surge watches will probably be issued on Monday for coastal parts of Texas and Louisiana, with the impacts expected to be felt from Tuesday night.

Residents tell of ‘apocalyptic scenes’ after more than 60mm of rainfall falls on Italian capital in less than an hour

Lightning has struck the Constantine Arch near the Colosseum in Rome during a violent thunderstorm, breaking off fragments from the ancient structure, officials have said.

The fragments were immediately gathered and secured by workers at the Colosseum Archeological Park, authorities in the Italian capital said. The extent of the damage, which occurred on Tuesday, was being evaluated.

“The recovery work by technicians was timely. Our workers arrived immediately after the lightning strike. All of the fragments were recovered and secured,” the park said in a statement.

Rome was hit by a sudden and powerful storm that dumped more than 60mm of rain in less than an hour, equivalent to a month’s rainfall in autumn. The city’s mayor, Roberto Gualtieri, described it as a “downburst”.

Corn sweat: crop moisture amplifies humidity and heat in US midwest

Posted on by

Moisture from crops drives up already high humidity in areas where 55 million are under extreme heat alerts

You won’t believe your ears, but corn is making the extreme heat the US midwest is battling feel more intense, according to experts.

The moisture – or “sweat” – that corn and other crops release in high temperatures is contributing to the humidity in the air in the midwest US, where 55 million people have been under alerts for extreme heat in recent days. The increase in moisture pushes up dew points, making it harder for water vapor to condensate – and for it to feel cooler.

Weather tracker: Flooding may hit Florida and Georgia as Storm Debby intensifies

Japan suffers under extreme heat but cooler conditions in Europe provide welcome reprieve at Olympics

Significant flooding may be about to hit parts of Florida and Georgia. Over the weekend, Tropical Storm Debby developed and intensified in the eastern Gulf of Mexico, moving slowly northwards off the west coast of Florida. At the time of writing, forecast models were indicating that the storm was likely to develop into at least a category 1 hurricane before making landfall on Monday, with sustained winds in excess of 75mph. As the storm encounters the very warm coastal waters off western Florida, it may briefly develop into an even stronger storm.

The eye of the hurricane is expected to landfall around the Florida Big Bend region before crossing northern Florida, Georgia, into the eastern Carolinas, and into the Atlantic, during Tuesday and Wednesday. As well as potentially damaging winds, storm surge warnings are in place in coastal regions of Florida. Rainfall totals in excess of 10-20in (250-500mm) may lead to serious flooding across parts of northern Florida, south-east Georgia and South Carolina.

Almost 34 million people in 65 major US cities, or 15% of the country’s population, are experiencing temperatures that are 8F higher than their surrounding areas, according to a new analysis from Climate Central, a non-profit research group.

That is largely due to built environments like parking lots and asphalt sidewalks, and a lack of trees, that contribute to what’s known as the urban heat island effect.
