Hot weather is rare for Anchorage which has reached an all-time high of 32°C (90°F) but in Alaska’s interior, heat is not unknown.
Fairbanks has previously topped out at 37°C (99°F) and the all-time Alaska state high was 38°C (100°F) in Fort Yukon from 1915.
Meteorologists say a strong high pressure system has been sitting stationary over the state creating the heat wave.
Smoke from wildfires has drifted into many communities creating air quality problems.
Neighbouring Yukon has also been affected by smoke with Whitehorse and Dawson City recording above normal temperatures in the high 20’s since late June.
Guadalajara was inundated with almost one metre of hail when a freak hailstorm moved through parts of Jalisco state on Sunday.
The governor posted photos on social media of buried vehicles, damaged homes and city workers alongside the Mexican Army shoveling the hail – even bulldozing it.
No reports of injuries or fatalities.
At 1,600 metres (5,000 feet) above sea level, meteorologists say high elevation played a role as one thunderstorm moved out and another one developed rapidly behind it bringing a huge quantity of small hailstones.
A rare June heatwave has blasted Europe with record breaking warm temperatures in numerous countries.
France recorded its highest temperature ever on Friday near the southern city of Montpellier at 45.9°C.

Snow falling in Washington, DC, USA, 15 Nov 2018 (Instagram)
A significant November snowstorm took meteorologists by surprise yesterday when more snow fell and for longer than originally forecast.
A Nor’easter moved up the U.S. Eastern Seaboard dropping 16 cm of snow on New York City which created commuter chaos with train delays and dozens of drivers trapped in their vehicles on treacherous highways.
While Washington, DC only picked up about 4 cm – the biggest November snowfall in three decades – it was to take road crews by surprise and some schools were closed.
The precipitation also included ice pellets and freezing rain with an eventual changeover to rain.
The storm also brought between 10 and 20 cm of snow across Southern Ontario with Toronto Pearson Airport picking up 11 cm.
The same system is now impacting the Maritimes.
Damage from Leslie in Lisbon, Portugal, 14 Oct 2018 (Reuters)
After swirling in the mid-Atlantic Ocean for weeks, Leslie hit the northwest coast of Portugal on Sunday delivering heavy rain and wind gusts up to 176 km/h.
The tropical storm uprooted trees, damaged cars and homes and local flooding was reported.
As Leslie exited Portugal and moved across northern Spain, the remnants of Michael were being felt in the same area of the Iberian Peninsula.
Meteorologists say this is the first time in recorded weather history that the remnants of two hurricanes have impacted Spain at the same time.
