Headline blocklist

Default: Match nothing (/(?!)/)

Example

Ignore warnings that contain the word corona

Regex: .*corona.*
Headline: corona-verordnung des landes: warnstufe durch landesgesundheitsamt ausgerufen

Affected area filter

This filter whitelists warnings based on the affected area. In other words, if the regular expression matches the area, the warning will be displayed.

Regex: .*nagold.*
Areas: gemeinde oberreichenbach, gemeinde neuweiler, stadt nagold
