The storms are expected to bring up to 40 mm of rain, small hail, and wind gusts reaching 70 km/h, preceding a period of anticipated cooling.
High Temperatures and Heat Stress
Before the storms arrive, meteorologists warn of significant heat stress affecting the population. On Thursday, July 16, and Friday, July 17, residents in the Elbe basin (Polabí), southern and central Moravia, and the Ostrava region face elevated health risks due to the influx of warm, humid air.
Daytime temperatures in southern and central Moravia, as well as parts of Silesia, are forecast to exceed 30 °C on Friday. In southern Moravia, local temperatures could climb toward 35 °C, according to CHMI reports.
Did You Know? The current weather pattern is characterized by an influx of warm and humid air, which is creating a high-stress environment for humans before the meteorological transition to cooler conditions occurs.
Fire Risks in Southern Moravia
Beyond the immediate storm and heat warnings, the CHMI maintains a standing alert for an increased risk of wildfires in parts of southern Moravia. Specifically, the Znojmo and Břeclav districts remain under caution until further notice. This heightened fire danger is driven by persistent drought conditions combined with stronger wind patterns.
The transition to cooler weather, while potentially mitigating heat stress, brings its own set of hazards, including localized flooding and wind damage from the projected 70 km/h gusts.
