Paragliders who use Windy
@idefix37 Totally agree on "the situation is very commonplace". The intention was to debunk the upcoming tabloid news I believe will come sooner or later. And yeah, I did not-so-clear could-be-sensational headline on purpose ;) But the article, far from sensational imho...
Think of it just as a unique opportunity to see TS Chantal and Greta in one picture.

Before you look at the satellite imagery below, where you can see the Tropical Storm Chantal just 700 miles away from the yacht on which Greta Thunberg sails to NY, let me make it clear: If you expect a tabloid-style alarmist kind of story, I will disappoint you. The team are professionals and can cope with the situation.

Actually, here's what Axel told us on TS Chantal:
Chantal is working very well to our advantage, and we positioned Malizia there to ride the Easterly winds to have a comfortable downwind passage on it's Northern end. We are currently at a separation point, a faster option would go further North, but the safer and more comfortable route a bit further South.
Here's the satellite loop from 21 August 2019, 8:45 a.m. to 2:35 p.m. UTC. Don't miss the weather update below.
Also don’t forget to read our previous coverage of Greta’s 3,000 miles long journey, watch the footage of her departure from Plymouth, and check out the Windy founder’s message to Greta here.
12 hours satellite loops (visible, unenhanced infra, color-enhanced infra+) 21 Aug 2019 4:30 am - 4:20 pm UTC. Track the path of TS Chantal with Windy Hurricane Tracker.
Robb Manes have shot quite funny weather-related video. No wonder it went viral overnight. The title says it all: The Great Mattress Migration of 2019.
The mattresses had been set out for an event called 'The Bed Cinema' later that day, according to local reports.

Northern Rivers Zone NSW RFS (Rural Fire Service) shared this aerial-view footage of a dust devil, that formed during the Northern Rivers Fires at Bungawalbin-Whiporie Rd. Below, you can watch the video, that was taken from Firebird 200 Iroquois UH 1-B on August 15th, 2019.
A dust devil is a strong, well-formed, and relatively long-lived whirlwind, ranging from small (half a metre wide and a few metres tall) to large (more than 10 metres wide and more than 1000 metres tall). The primary vertical motion is upward.

A large-scale upper trough extends across the NW half of Europe with its cold front from Finland, Baltic States, Poland, Alpine region, to N Spain.
Cold airmass convection is mostly found over S and W Scandinavia. An upper cold pool is over Turkey. Warm moist surface air converging along the east side of the front and moderate lapse rates set up 500-1000 J/kg MLCAPE, the maximum over E Poland.
A minimum in lapse rates is predicted over the central and eastern Alps to Czech Republic. An Atlantic shortwave trough comes to N Spain by the end of the period. In all level 1 and 2 areas deep layer shear is 15-20 m/s, sufficient for some supercells producing large hail.
The direction of shear and storm motion is mostly along the cold front, promoting linear convective systems with storm-relative inflow vectors from the warm side.
With moderate shear the large hail threat is significant and convective development is forecast to be widespread. Severe wind gusts may occur but CAPE and delta theta-e appear a bit limited.
Slower storm motion and weaker lapse rates can cause excessive local rainfall, while in the France/Italy border region large hail is more likely.
Capped during most of the day, energy can build up over the Ebro Valley to be released at night. Strong 25 m/s 0-6 km shear suggests supercells are quite likely with large hail and possibly severe wind gusts or excessive rainfall.

19 August 2019 - About 8,000 people have been evacuated from Gran Canaria, as wildfires rip through the island. According to the reports, the fires which started on Saturday, has burned more than 3,400 hectares (8,400 acres) of land, and were described as unstoppable.
Ángel Víctor Torres, the head of the Canary Islands government, described the situation as an environmental disaster, and said it had been “neither contained nor controlled”.
Ten planes and helicopters, as well as about 700 firefighters on the ground including 200 from the military, were deployed, according to this BBC report.
A "before/after" satellite imagery processed by Pierre Markuse reveals the extent of the wildfires.
