06:50 , Aisha Rimi

A dangerous heat wave hit much of the Midwest and South on Tuesday, with temperatures hitting triple digits in Chicago and combining with the humidity to make it feel even hotter there and in other sweltering cities.

More than 100 million people were expected to be affected by midweek and authorities warned residents to stay hydrated, remain indoors when possible and be aware of the health risks of high temperatures.

Strong storms brought heavy rain and damaging wind to many of the affected areas on Monday, and more than 500,000 customers remained without power early Tuesday evening, including more than 350,000 in Ohio, according to

Excessive heat warnings are in effect for much of Illinois and Indiana along with parts of Minnesota, Iowa, Michigan and Ohio from Tuesday through Wednesday night according to the National Weather Service.

Heat index values — which take into account the temperature and relative humidity and indicate how hot it feels outdoors — approached and topped 40C in some locations, including Chicago, the weather service said.

A heat advisory also was issued, stretching from as far north as Wisconsin down to the Florida Panhandle on the Gulf coast.

Northern Arizona watches winds as Western wildfires blaze

05:50 , Aisha Rimi

Calmer winds and cooler temperatures on Tuesday allowed firefighters across the western US to get a better handle on blazes that have forced hundreds of people from their homes.

As red flag warnings expired and winds died down in northern Arizona, firefighters took advantage of the weather changes to attack a 31-square-mile (81-square-kilometer) blaze by air and at the fire’s edges.

The forecast for later this week called for a chance of showers, which could dampen the blaze but might bring the chance of new fires from lightning strikes.

Meanwhile, authorities have downgraded evacuations for the larger of two wildfires burning on the outskirts of Flagstaff, Arizona.

Visitors were evacuated from parts of Yellowstone National Park on Monday after heavy rain brought flooding and mudslides to the country’s oldest national park.

Roads have been washed out and the park closed after the powerful floods swept through, upending operations in the busy park.

The Yellowstone River in Corwin Springs, Montana surpassed its previous record high water level by at least two feet, according to the US Geological Survey.

Parts of the South East, London and Wales could reach at least 27C and could rise to 34C on Friday, hotter than Portugal, Jamaica, Costa Rica, the Canary Islands and Cyprus.

Sunbathers have been warned in advance against “overdoing it” as the temperatures soar.

Craig Snell, a Met Office forecaster, said: “Very high UV levels are expected in the south this week, meaning people should really avoid being in the sun during the midday hours.

“Wearing sunglasses, a shirt, a hat and sunscreen are essential to protect the eyes and skin, and drinking lots of water is important – long exposure to the sun can be dangerous.

“People should avoid overdoing it. We all love the sunny weather, but being sensible can help you avoid a nasty sunburn.”

Festival-goers attending Glastonbury can expect warm weather during the long weekend between 24 to 26 June. However, the Met Office forecasts possible rain and thunderstorms as well.

The forecaster said: “Temperatures will be average for most, but warmer in the south, with possible thundery conditions bringing potentially hot temperatures for southern regions.

“High pressure is likely to persist and move westwards through this period, bringing more unsettled and occasionally showery conditions across the UK associated with a north-westerly wind.”

UK heatwaves not a cause for celebration

Tuesday 14 June 2022 18:24 , Aisha Rimi

Much of the UK press is breathlessly reporting the nation is set for the ‘hottest summer ever’ with ‘at least five heatwaves’ on the horizon.

News outlets published pictures of bikini-clad beachgoers enjoying the sunshine, and quoted James Madden, forecaster for Exacta Weather, who said: “The overall summer forecast is now pointing towards at least four or five major heatwaves.”

But what many of these joyful news reports fail to mention is that these heatwaves are a direct result of climate change – and could cause sickness and death.

UKHSA and Met Office issue level 2 heat-health alert

Tuesday 14 June 2022 17:57 , Aisha Rimi

The forecaster has issued a level 2 heat-health alert warning ahead of rising temperatures predicted for later this week.

On the four-level heat-health alert scale designed to help healthcare workers manage through periods of extreme temperatures, level 1 is the lowest warning and is the minimum state of vigilance used during the summer months.

RSPCA issues warning

Tuesday 14 June 2022 15:50 , Matt Mathers

The RSPCA has issued a warning to pet owners about the incoming heat.

Esme Wheeler, RSPCA dog welfare specialist, said: "The truth is walking dogs in hot weather can be a silent killer.

"While the majority would never leave our dogs in a car on a hot day, or even take our dogs for a really long walk in the heat, many people may still be putting their dogs at risk even on a short walk, or taking them to places such as fields and beaches with little or no shade.

"We have long-campaigned that dogs die in hot cars, but this year we're highlighting that dogs die on hot walks, too. The message remains very simple - never leave a dog in a hot car because 'not long' is too long, and when it comes to walks, 'if in doubt, don't go out."'

RNLI issues warning as temperatures surge

Tuesday 14 June 2022 14:30 , Matt Mathers

The RNLI has warned people to be careful near water as the weather heats up this week.

Gabbi Batchelor, Water Safety Education Manager at the RNLI said: “With summer arriving and a heatwave forecast, we want to remind everyone to stay safe at the coast.

“It is important that anyone visiting the coast understands the risks of the environment. It can be very unpredictable, particularly during early summer when the risk of cold water shock significantly increases, as air temperatures warm but water temperatures remain dangerously cold.

“If you get into trouble in the water, Float to Live: lean back, using your arms and legs to stay afloat. Control your breathing, then call for help or swim to safety. In a coastal emergency, call 999 or 112 for the Coastguard.’

The RNLI is also reminding people to visit a lifeguarded beach and swim between the red and yellow flags this summer.

Gabbi adds: “With hot weather forecast, we know lots of people will be heading to the coast. To help stay safe, we’d encourage people to visit a lifeguarded beach and swim between the red and yellow flags. It’s important to remember to swim between those flags because lifeguards put them on the safest stretch of water and patrol this area.”
