North Atlantic Systems
See also: History of Atlantic hurricane warningsThe following terminology used by the US National Hurricane Center is the model for countries around the North Atlantic and in the Caribbean basin. This is also used for the Pacific coasts of Mexico, Central America, southern California, and Hawaii. The timing and naming of tropical cyclone advisories, watches, and warnings has changed over time. In 1958, tropical cyclone advisories were issued every six hours starting at 0400 UTC each day. During 1967, hurricane watches were used to designate areas where hurricane conditions were possible in the next 24 hours, while hurricane warnings indicated areas where the hurricane center should cross the coast. Small craft, gale, and storm warnings were issued for hurricanes not expected to make landfall. By 1987, the definition of tropical cyclone watches had changed to areas where gale or hurricane-force winds were possible within 36 hours, with warnings issued when gale or hurricane-force winds were expected within 24 hours. In 1987, gale watches/warnings were renamed tropical storm watches/warnings. In 1991, advisory timing shifted back to every six hours starting at 0330 UTC every day. In 1992, advisory timing changed to every six hours starting at 0300 UTC each day. The length of time used for watches and warnings changed again in 2010, with watches using a 48 hour time frame and warnings using a 36 hour time frame.

Famous quotes containing the words north, atlantic and/or systems:
“We have heard all of our lives how, after the Civil War was over, the South went back to straighten itself out and make a living again. It was for many years a voiceless part of the government. The balance of power moved away from it—to the north and the east. The problems of the north and the east became the big problem of the country and nobody paid much attention to the economic unbalance the South had left as its only choice.”
—Lyndon Baines Johnson (1908–1973)
“Obscurest night involv’d the sky,
Th’ Atlantic billows roar’d,
When such a destin’d wretch as I,
Wash’d headlong from on board,
Of friends, of hope, of all bereft,
His floating home for ever left.”
—William Cowper (1731–1800)
“Our little systems have their day;
They have their day and cease to be:
They are but broken lights of thee,
And thou, O Lord, art more than they.”
—Alfred Tennyson (1809–1892)
