Wind first or water first — the question the settlement rests on
When a hurricane makes landfall, the wind arrives before the surge. If wind opened the roof and rain destroyed the interior before water rose in the street, that interior damage is a windstorm loss. If the surge got there first, it is flood. Anti-concurrent causation clauses let a carrier deny the whole loss where covered and excluded perils combined, which is why this sequence gets fought over.
It is provable. High-water marks against the height of interior saturation, the direction of material failure, the debris line and the storm's recorded timeline over the address together establish the order of events. That evidence exists at the property for a short window before clean-up removes it.
