Such, then, were the meteorological conditions off the coast, awaiting the attack of the advance guard of this long line of cold northwesterly gales,--conditions still further intensified by the freshening gale that sprung up from the southeast at its approach, drawing re-enforcements of warm, moist ocean air from far down within the tropics. The energy developed when storm systems of only ordinary character and severity reach the Atlantic on their eastward march toward northern Europe is well-known, and need not be referred to further: let us now return to the consideration of this storm which is advancing toward the coast at the rate of about 600 miles a day, in the form of a great arched squall whose front is more than a thousand miles in length, and which is followed, far down the line, by northwesterly gales and temperatures below the freezing point.
Sunday afternoon, at 3 o'clock, the line of the storm center, or trough, extended in a curved line, convex to the east, from Lake Ontario down through New York State and Pennsylvania, along about the middle of Chesapeake Bay to Norfolk, across North Carolina to Point Lookout, and thence down through eastern Florida to Key West. Northeasterly, easterly, and southeasterly gales were therefore felt all along the coast from the Gulf of St. Lawrence to the Florida Keys, except in the bight between Lookout and Cañaveral, where the barometer had already reached and passed its lowest point and the wind was northwest, with much cooler weather. Reference to the Barometer Diagram shows pretty clearly that the trough passed Norfolk a short time before it reached Hatteras, where the lowest reading was undoubtedly lower, the evening of the 11th, than it was at Norfolk.
By 10 P.M. the line has advanced as far east as the 74th meridian. Telegraphic reports are soon all in from signal stations along the coast. The barometer is rising at Hatteras and Norfolk and still falling at Atlantic City, New York, and Block Island, but there is little or no indication of the fury of the storm off shore along the 74th meridian, from the 30th to the 40th parallel, where the cold northwesterly gale is sweeping over the great warm ocean current, carrying air at a temperature below the freezing point over water above 75° Fahrenheit, and where the barometer is falling more and more rapidly, the gale becoming a storm, and the storm a hurricane. Nor are there any indications that the area of high barometer about Newfoundland is slowing down, blocking the advance of the rapidly increasing storm, and about to hold the center of the line in check to the westward of Nantucket for days, which seem like weeks, while a terrific northwest gale plays havoc along the coast from Montauk Point to Hatteras, and until the right flank of the line has swung around to the eastward far enough to cut off the supply of warm moist air pouring in from the southeast. Long before midnight the welcome "good night" message has flashed along the wires to all the signal stations from the Atlantic to the Pacific slope, whilst at sea, aboard scores of vessels, from the little fishing-schooner and pilot-boat to the great transatlantic liner, a life-or-death struggle with the elements is being waged, with heroism none the less real because it is in self-defence, and none the less admirable because it cannot always avert disaster.
