For the past 3 days, a weather worthy of the best ski resorts has settled in the capital. Snow, gray skies, and polar cold have led to the implementation of a snow and ice orange alert across the entire region, which definitely impacts traffic, whether it's by road, air, or rail. And since this morning, many Parisians can attest, it’s sometimes a battle to get to work. Let’s take stock together.
Transportation options at a standstill
For the past 3 days now, the people of Île-de-France are holding their breath. For some, it’s about whether they’ll find a bus or a RER to get home. For others, a train to go skiing, or even a plane to head off on vacation. Well, whatever your situation, we’d better warn you, today, don’t count too much on it. In fact, since this morning…The entire bus network of the region has been suspended by RATP for safety reasons. Traffic is also extremely disrupted on nearly all RER and Transilien lines, which are running at very reduced speeds. In the same vein, nearly 150 flights have been canceled departing from Roissy and Orly.

Subways in Trouble
On the side of the intra-city rail network, it's a bit of a mess too. Across all lines, a warning message states that traffic is disrupted on all lines due to weather conditions. Some lines are, however, a bit more affected than others, even if the reasons often mentioned aren’t always about snow. For instance, only line 6, which runs mostly above ground, is reporting disruptions directly related to the weather. However, the 5, 7bis, 9, and 11 lines are still in orange status as well. But things are changing quickly, and we're not out of the woods for more announcements in the coming hours.
