How does a storm come about

In storms and hurricanes with sustained high wind speeds, the wind pressure and the higher gusts that are attached to it are particularly problematic.
Caution: People are usually injured in storms by trees, falling or flying debris and objects.

Winds and gusts from a strength of 8 on the Beaufort scale become dangerous. The effect of the wind force is described as follows:

Beaufort scale

Strength Designation Impact m / sec km / h

0 - calm smoke rises vertically to 0.0 - 0.2 - 1
1 - soft draft Smoke deflection visible 0.3 - 1.5 - 5
2 - a slight breeze felt on the face 1.6 - 3.3 - 11
3 - weak breeze thin branches move 3.4 - 5.4 - 19
4 - moderate breeze Pennant stretched, loose paper flies 5.5 - 7.9 - 28
5 - fresh breeze larger branches move 8.0 -10.7 - 38
6 - strong wind strong branches are moving, flags rattling 10.8-13.8 - 49
7 - stiff wind trees move 13.9-17.1 - 61
8 - stormy wind cars skid 17.2-20.7 - 74
9 - Slight storm damage 20.8-24.4 - 88
10 - severe storm uprooted trees 24.5-28.4 - 102
11 - hurricane-like storm severe destruction 28.5-32.6 - 117
12 - hurricane devastation + 32.6 +117

Preventive protective measures:

  • Stable roof construction and solid anchoring in the masonry with the help of wall anchors, screws and metal straps.
  • Bracing of masts, antennas and chimneys to prevent long-period vibrations and periodic checking of such facilities.
  • In addition, scaffolding, billboards, awnings, party tents, cover plates and tarpaulins should be firmly anchored in warning situations
  • Protection against uprooted trees in the vicinity of the house by appropriate spacing or by cutting back trees near the building to a maximum ridge height.
  • As a preventive measure, you should put roofs and chimneys on loose roof tiles or metal sheets etc. at regular intervals. check.
  • Stocking of replacement roof panels and foils to temporarily avoid moisture damage in the event of damage.
  • Covering of glass surfaces in the private sector (roller shutters) and in trade, for example in greenhouses (hail-proof glass types).
  • Conversion to hail-proof roofs with concrete roof tiles, reinforced sheets or special foils with gravel fill and side cover.
  • Move unsecured objects that are outside the house in the garden to a safe place (e.g. garbage cans, laundry, flower pots, tools, garden furniture, etc.)!

Rules of conduct and tips in case of severe storms

  • Be careful when driving on particularly exposed road sections and bridges - especially danger for large trucks and caravans! Follow the tips from the motoring clubs!
  • Avoid driving through wooded areas and avenues!
  • Be careful with outdoor events - it is recommended that such events be canceled for safety reasons.
  • Close windows and doors (do not tilt them either)! If available, close the shutters or shutters!
  • Do not leave the protective living spaces in a storm - danger from falling debris, trees or electrical cables!
  • If your house is surrounded by tall trees, don't be on the top floor! Also avoid window areas that could break!
  • Avoid going to parks, wooded areas and cemeteries!
  • Don't be fooled by the sudden calm! Switch on the radio for more information about the weather development!
  • If you must be outdoors, avoid the vicinity of buildings, scaffolding, tall trees, and power poles!
  • Do not park vehicles near houses or tall trees! Park your vehicle in the garage! Do not use any underpasses for parking purposes in order to give rescue workers free access to the emergency locations.
  • Leave tents and caravans in storms as there is a risk of overturning due to insufficient anchoring.
  • Check your flashlights or emergency power supply before the storm - risk of power outages
  • Do not start any clean-up work until after the storm has ended. Make sure that there is sufficient distance from buildings that may be in danger of collapsing and from torn off power lines!
  • Also think of people around you who are in need of help or who do not understand German. They need your assistance.

Help with extreme weather events from the fire brigade

  • A nationwide fire brigade system guarantees quick help
  • In the event of a storm, a large number of damage reports can usually be made within a short period of time. This leads to a correspondingly high number of operations to be dealt with at the same time.
  • Under certain circumstances, the fire brigade's potential can be used to such an extent that there are longer waiting times for the helpers to arrive.
  • In principle, every call to the emergency number 122 is recorded and processed depending on the urgency.
  • It is important to describe the damage as precisely as possible, e.g. whether people are injured or there is another hazard.
  • On the basis of your description of the situation, the fire brigade decides on the urgency in order to respond quickly and effectively to every request for help, depending on the severity of the incident.
