Context & protective measures

The greatest danger is the health burden from persistently high day and night temperatures, which favour dehydration, heat stroke and circulatory problems. The elderly, the chronically ill, pregnant women and infants are particularly at risk.
Recommendation
Likelihood is rated medium and impact high. Prepare with targeted measures against heat stress and observe local outdoor fire bans.
What to do now
Drink enough, avoid the midday heat and physical exertion outdoors, keep living spaces cool by ventilating in the morning and shading during the day, and look after vulnerable people around you.
