St. Peter's Flood: A storm surge floods the Frisian coast, drowning 15,000 people.

St. Peter's flood refers to two separate storm tides that struck the coasts of Netherlands and Northern Germany in 1651. During the first storm tide, on 22 February, the East Frisian island of Juist was split in two. During the second disaster, on 4–5 March, the city of Amsterdam was flooded.

The German Bight ; West Frisian: Dútske bocht; North Frisian: Schiisk Bocht; sometimes also the German Bay) is the southeastern bight of the North Sea bounded by the Netherlands and Germany to the south, and Denmark and Germany to the east. To the north and west it is limited by the Dogger Bank. The Bight contains the Frisian and Danish Islands. The Wadden Sea is approximately ten to twelve kilometres wide at the location of the German Bight. The Frisian islands and the nearby coastal areas are collectively known as Frisia. The southern portion of the bight is also known as the Heligoland Bight. Between 1949 and 1956 the BBC Sea Area Forecast used "Heligoland" as the designation for the area now referred to as German Bight.

February 22 is the 53rd day of the year in the Gregorian calendar; 312 days remain until the end of the year.
