A rise in sea level caused by a storm, distinct from a tsunami. Often used in meteorological contexts.
See also: 高潮 (たかしお)
Coastal areas were flooded by the storm surge caused by the typhoon.
高潮 is a more common term for storm surge, while 暴風津波 is a less frequent synonym that explicitly includes the characters for 'storm' and 'tsunami'.
Compound of 暴風 (storm) and 津波 (tsunami), literally 'storm tsunami'. The exact historical derivation is uncertain; the term is used in modern Japanese to refer to a storm surge.
