After the good weather comes the rain. For Belgium, it will be Sunday night on a Monday since precipitation is expected in part of the country. Bad news, as one had to suspect, these will be stormy. David Dehenauw also confirmed it to RTL while specifying that it would be “local stormy showers”. “It is a disturbance which comes from France and which will arrive during the night in the extreme south of the country, and which will progress towards the other regions this Monday”, he explained.
If the storms therefore invite themselves to part of Belgium on Monday, the IRM meteorologist predicts another more complicated day. “I think that this Monday, we will have fairly local stormy showers, later a little more agreed over the hours, but not in all the municipalities. Tuesday, it will be hot and dry again, but Wednesday and Thursday, on announcement of the stormy showers more adopted on the entire country. With precipitation that could be quite intense locally. I’m not going to say heavy rainfall, because when I see the patterns, it’s between 5 and 30 or 40 millimeters over the whole week. »
It will therefore be necessary to go through these showers before being able to enjoy the sun and the heat again. A heat wave which will also continue for a few days according to the spy of David Dehenauw.
The 1722 activated
The call number 1722 for non-emergency fire service was activated due to a risk of storm or flooding on Sunday by the FPS (federal public service) Interior, the Royal Meteorological Institute (IRM) having issued a bad weather warning.
The 1722 has for but to avoid that the emergency numbers are overwhelmed by calls for interventions which can however wait. In the event of storm damage or water damage for which the assistance of the fire brigade is required, this number should therefore be dialed. If a life is in danger, call 112.
The FPS also recommends using the 1722.be electronic counter, considered to be “the most direct way to request help from the firefighters in situations where no life is in danger”.
The 112 emergency centers and the fire brigade always give priority to people whose life is potentially in danger. “They analyze situations on a case-by-case basis and determine who needs to be rescued first. During a storm or a flood, they have to deal with many requests at the same time”, underlines the federal public service. “Be patient and don’t call back to find out when help will arrive,” he asks.
The activation of the number 1722 is preventive when a storm or heavy rain is announced. This activation in no way predicts the seriousness of the warning and the extent of any damage, recalls the FPS Interior.
Belgium still on alert
This Sunday the heat wave reached its peak, with temperatures of 33 or 34 degrees in many places, see 35 degrees locally. In the central provinces of the country, the heat wave will continue until the middle of the week. It will be a little less hot, but the highs will remain above 25 degrees. At the sea and in the Ardennes, the mercury will drop below 25 degrees in most places this Monday, which will result in the end of the heat wave in these regions.
It is still advisable to take the following measures: drink regularly, dress lightly, spend your days in cool places, comply with the usual rules of health, split food portions, avoid outside heat by closing doors and windows. Be careful with fire outbreaks in nature and take care of animals by giving them water and avoiding leaving them in the sun.
