Kicking Horse, December 20th
Kicking Horse, December 20th
North America Overview

It's been a week of improvements across North America in almost all regions. The big change for the better is currently underway along the Pacific coast. It's the first of a series of storms set to continue over the next few days, which will hopefully bring snow rather than rain to lower elevations right down to California, and potentially five feet or more of it for some, really transforming conditions from the almost snowless state up to now.

Resorts have started opening and reporting up to 48 inches in 48 hours, so it's looking promising initially. Not so much will make its way to the Rockies, but things are slowly improving here too on the US side of the border, whilst on the Canadian side, up to a metre more snowfall has been reported, so steep and deep terrain is go. On the East Coast, a warm weather blip ended last week, but it's been back to mostly cold and snowy since.

It's not quite a white Christmas, but it's probably as close as you can get in several places on the eastern Costa del Sol in Malaga province today. A storm that deposited hail stones surprised many residents during the afternoon of this Wednesday 24 December, Christmas Eve. Just after 1.30pm hours, a heavy rain and hail storm surprised residents of the Axarquia area, in towns such as Rincón de la Victoria, Vélez-Málaga, Benajarafe and Cajiz and also in inland villages such as Almáchar and El Borge.

A waterspout was even clearly visible near Chilches, captured on video by Lui G. Marín while he was with his family. "It surprised us. We were watching the hail and we weren't expecting it. We saw it moving from one place to another across the sea, but it didn't touch land," he told SUR.

Heavy rains lashed the United Arab Emirates and other Gulf states on Friday, flooding roads and disrupting flights at the world's busiest international airport, while parts of neighbouring Saudi Arabia and Qatar were blanketed in unexpected snow.

UAE airport authorities cancelled or delayed dozens of flights as the heaviest rainstorm in months hit the desert nation. Dubai's Emirates airline axed 13 flights on Friday, with disruptions also reported at the airport in neighbouring Sharjah after an overnight downpour brought lightning and thunder.

"Some flights... are cancelled or delayed due to adverse weather," a Dubai Airports spokesperson said. The scenes evoked memories of April 2024, when record rainfall caused widespread flooding and forced the cancellation of over 2,000 flights in Dubai.

On Thursday, Dubai police had urged residents to stay home unless "absolutely necessary." By Friday morning, Sharjah's main street was completely flooded, and water-pumping trucks were deployed across Dubai to clear blocked roads.


Comment: The Khaleej Times reported:

The National Centre of Meteorology confirmed that the main wave of rainfall had passed, with Ras Al Khaimah's Al Ghazlah area recording the highest total at 127mm. The emirate also saw landslides and gushing wadis, prompting authorities to close several roads and Jebel Jais for safety.
