what is a washover fire

Overwash occurs during intense coastal storms when the combination of storm surge and storm waves overtops the beach crest and dune topographic highs of a barrier island and deposits washover sand into back barrier marshes and bays, contributing to the landward migration (rollover) of the barrier island (Donnelly et al., 2009 ). Fire is the result of a chemical reaction called combustion. Some dry powder extinguishers are suitable for low-voltage situations. Overwash areas, which are indicators of hazards to coastal development, are typically characterized by low elevations adjacent to the back beach, absence of dunes, and barren or sparse vegetation.
