Special advisories are broadcasted whenever there is a significant change in weather conditions. The building surface through which wind tries to infiltrate during strong winds. Wind seeps in through the weakest elements, e.g., openings, windows and doors. The internal pressure build up is what causes roofs to blow off wood frame buildings. Once the roof is blown, the whole structure disintegrates.
Shutters help delaying the wind speeds at which the internal pressures reaches that critical point.
Wind is blown in the windward side and out from the leeward side of the building. The practice of leaving some openings open on the leeward side can be very dangerous as the wind changes direction as the two sides of the hurricane eye walls cross over the building. The pressure at the center of a hurricane measured in millibars. The lower the pressure, the higher the wind speeds. Refers to the abnormal warming of the equatorial eastern Pacific Ocean that changes and disrupts global climate conditions.
