A new heat wave expected in Belgium: almost the entire country placed on alert by the MRI

Over the next few days, a broad area of ​​high pressure, initially centered over the British Isles, will slowly expand into southern Scandinavia.

It will be the source of gradually continental currents, warmer and warmer, in our regions. From this Sunday, the maxima will already reach or exceed 25 degrees in many places. The rise in temperatures will then continue with maximums exceeding the 30 degree mark in most regions in the middle of the week.

At the end of the week and/or the weekend, they could even approach, or even locally exceed, 35 degrees. However, during the first part of the week, a north to northeast breeze will keep the weather cooler on the coast.

“Given these forecasts, the probability of a heat wave beginning this Sunday or Monday (depending on the region) is very high for the interior of the land, and leads us to issue a yellow level warning there”, indicates MRI.

This wave could extend beyond the next weekend. Following the highs of more than 32 degrees in sight for the weekend, the warning level is orange from Wednesday for the interior of the country. It will be necessary to take the necessary measures to limit the impacts linked to this new period of high heat.

This warning may be reviewed as the situation evolves.
