Wildfire and record temperatures in Canada are generating ‘fire-breathing’ pyrocumulonimbus thunderstorms

Mass evacuation underway as Philippines raises danger level for the Taal volcano

Authorities in the Philippines started evacuating thousands of people on Thursday after the alert status was raised on a restive volcano that spewed a 0.62 mile high plume of gas and steam.

In January last year, Taal shot a column of ash and steam almost 10 miles into the sky, which forced more than 100,000 people to abandon their homes

The alert for the Taal volcano, about 70 km (45 miles) south of central Manila, moved to level 3 from level 2 on the 5-level scale, which the seismology and volcanology agency said meant a “magmatic intrusion” at the main crater “could further drive succeeding eruptions”.

Taal is one of the world’s smallest active volcanoes. Despite standing at only 1,020-feet, it can be deadly and an eruption in 1911 killed more than 1,300 people…

Wildfires and record temperatures in Canada are generating ‘fire-breathing’ pyrocumulonimbus thunderstorms

As heat and smoke from large fires rise skyward, they can create firestorms comprised of what are known as pyrocumulonimbus clouds. These thunderheads produce their own weather, including tornadoes in rare cases, which can then spark new fires. It’s a vicious cycle.

Sometimes, if the convecting air in a pyrocumulonimbus cloud bank forms a swirling, circular column, the storm can morph into a “fire tornado” – a twister of fire.

Temperatures in Lytton, 153km south of Vancouver, hit 121.2 degrees Fahrenheit (50 degrees Celsius) on Tuesday – a new national record. The heat wave preceded a wildfire that prompted the town’s mayor to issue an evacuation order for all 250 residents. As of Thursday morning, the 20,000-acre blaze had burned 90% of Lytton, according to local outlet City News…
