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 ). Since the washover pipe is relatively thin-walled and large in diameter, and may be prone to sticking itself, the washover operation is usually reserved as a measure of last resort before abandoning the fish altogether. The heat of the flame itself keeps the fuel at the ignition temperature, so it continues to burn as long as there is fuel and oxygen around it. Burning, injuring, and even killing people.
