Nurses and doctors have been delayed by temporary airport closures in South Florida, unable to travel to those in Haiti injured by the hurricane that has killed hundreds. Warehouses collecting medicine, food and other supplies have been at a standstill. As a humanitarian crisis unfolds in their homeland, Haitian-Americans are eager to help. But Matthew, in addition to threatening the U.S., is complicating the relief effort.
In simple terms, storm surge is the abnormal rise of sea water. However, it is so complicated to predict that forecasters removed flooding references in a 2010 revision of the five-category system for describing the damage possible at various hurricane wind speeds. Earlier this year, Hurricane Hermine was the first time forecasters experimented with storm surge watches and warnings for the public. The advisories, which are separate from watches and warnings about storm wind speeds, may become fully operational next year.
