During the next twenty years, blizzards, hail storms, tornadoes and sudden wind storms of other kinds gave the new weather service a great deal of trouble. They brought a vivid realization of the great variety of surprises that lay in wait for the storm hunters. No sooner had they found rules for the issuance of warnings than a new kind of peril came along. The service had been in the Signal Corps of the Army, but in 1891 it was turned over to the Department of Agriculture because of its value to the farmers. The desperate struggle against storms continued, with many experienced weathermen feeling very discouraged about the whole business. And then on February 15, 1898, the Battleship Maine was sunk in Havana Harbor and war with Spain loomed on the horizon.

On April 25, the United States declared war. The Spanish fleet left the Cape Verde Islands for Cuba and American warships departed for the West Indies, to prepare the way for the movement of troops for the coming campaign in Cuba. It was June 29, however, before the transports arrived at Santiago, carrying seventeen thousand officers and men to support the United States fleet. By that time, the commanders on both sides had begun to worry about storms, for the first hurricanes had appeared as early as June in some years, bringing destructive winds and torrential rains to some parts of Cuba and the surrounding area.

Willis Moore was Chief of the Weather Bureau. He had been a sergeant in the Signal Corps, transferred when the service was put in the Department of Agriculture. He knew very well the difficulties of tracking storms and especially in the West Indies, where only scattered weather reports could be obtained by cable from some of the islands. A bad hurricane could easily sneak up on the American forces through the broad waters of the Caribbean, a predicament likely to arise if the Weather Bureau depended on cable messages from native observers.

Moore carried his worries to James Wilson, Secretary of Agriculture, who decided that they should go to the President. At the White House, they soon had an audience with McKinley, and Wilson presented the case. Moore had maps, charts and data on hurricanes and the disasters they had caused in the West Indies. Also, he had sketched a plan for a cordon of storm hunters on islands around the Caribbean, to protect the American fleet. He said that armadas had been defeated, not by the enemy, but by the weather. He thought it probable that as many warships had been sent to the bottom by storms as by the fire of the enemy. The President listened respectfully at first, then with impatience at the lengthy discussion. He had made up his mind. Interrupting Moore, he got up, sat on the corner of his desk and declared:

“Wilson, I am more afraid of a West Indian hurricane than I am of the entire Spanish Navy. Get this service started at the earliest possible moment.”

Moore ventured to say, “Yes, indeed, Mr. President, but the Weather Bureau will need the authority of Congress to organize a weather service on foreign soil.”

The President told Wilson: “Report to Chairman Cannon of the Appropriations Committee at once. They are preparing a bill to give me all necessary powers to conduct the war and this authority can be included.”

It was soon done. As a part of the plan, a fast cruiser was stationed at Key West, to carry the news to the fleet immediately, in case the Weather Bureau predicted a hurricane. In that event, the fleet might have abandoned the blockade, to get sea room and avoid the center of the storm.

With this authority, the Weather Bureau moved swiftly to station men and equipment on the islands. Letters had to be written to European countries for permission to send observers into their possessions. But although the bill containing the authority only passed Congress on July 7, observers arrived as follows: July 21—Kingston, Santiago, Trinidad, San Domingo, St. Thomas; August 11—Barranquilla; August 12—Barbados; August 18—St. Kitts; August 29—Panama.

Land fighting continued in the West Indies until August 12, but the Spanish fleet was destroyed on the morning of July 3. They made a desperate effort to escape from the harbor at Santiago, were shelled by American warships, and all were disabled or beached. Up to that time there had been no tropical disturbances in the region. A small one hit near Tampa on August 3. Another small but vicious hurricane swept the coast of Georgia on August 31. The first big one of the 1898 season raked Barbados, St. Vincent and St. Lucia on September 10 to 11, and disappeared east of the Bahamas.
