Belgium narrowly escapes (for now) ‘polar depression’, Netherlands should prepare for rare natural phenomenon

On Wednesday a “polar low,” a rare natural phenomenon that brings lots of snow, is on its way to the Benelux. Ours seems to get away with it (to a large extent), but in particular the north of the Netherlands can be covered in a thick layer of snow. “And on Friday there is already a new opportunity for Belgium as well.”

The “Polar Low” is a small-sized area of ​​low pressure with a warm core. It is rare—for example, the previous four or five winters did not happen—because very specific conditions must be met: warm sea water, with very cold upper skies. “That was the case on Tuesday,” says Nicholas Rose Fan. severe weather. The water in the North Sea was still between 10 and 12 degrees, while it was -37 at 5.5 km. This led to a formation like this one in the north-east of Scotland polar depression. “

This low pressure area is now heading towards the Benelux. “However, the most recent weather models predict that the system will deflect over northwest Holland toward Denmark,” Rose says. “In the afternoon, the north of the Netherlands – especially the interior – can be hit with gusts of up to 90 kilometers per hour and heavy snow showers.”

“With buckets from heaven.”

“Heavy” is not even an exaggeration. “In an area that is already below a cloud belt with snow, 5 to 10 centimeters of snow can easily fall per hour,” says Rose. “Then you really fall from the sky.”

Our country seems to be escaping direct impact this time, although the provinces of Antwerp and Limburg may have to deal with some “branches” tonight and the next night. “We might see some winter rain here and maybe some snow. How long and if that snow will stay is yet to be predicted. With temperatures approaching the freezing point, it may therefore be necessary to pay attention again during the morning rush hour on the morning of Thursday “.

Friday

As valid conditions are still met, a new small sized depression core is likely to form over the Netherlands on Friday. Maybe this will be another one polarlo, although this is not yet certain,” Rose says. “Is he coming to Belgium? This is still looking at coffee grounds. We usually only know a few hours in advance how it’s done polarlo You will develop.”
