Thunder (Hearing)

Last Updated On: 10/30/13

When hearing thunder, one should say the Brocho: Shekocho Ugevuraso Malei Olam

The Brocho should only be said once a day unless the sky cleared, and then the storm started anew. If it is the next day the Brocho is said again (even if the sky did not clear).
