The United States Naval Meteorology and Oceanography Command (NMOC) provides critical information from the ocean depths to the most distant reaches of space, meeting needs in the military, scientific, and civilian communities. 

A COLD northeast storm of wind, rain and snow raged along the coast of New England during the latter part of March, 1830, producing a great tide, which in some parts exceeded the highest tide remembered there. The storm began on the morning of Friday, the twenty- sixth, and continued till one o'clock in the afternoon, the tide being at its height at noon of that day.

IT was said centuries ago that lightning strikes churches oftener than residences. In reference to this saying Cotton Mather wrote in the seventeenth century: " New England can say so. Our meeting houses and our ministers' houses have had a singular share in the strokes of thunders." This summer of 1770 seemed to prove these assertions, and if Mather had then been alive he would doubtless have mentioned this evidence in support of his claim. The principal showers during the summer occurred as follows.

THE winter of 1786-87 set in very early. At Warren, in Maine, on the fourteenth of November the St. George's river was frozen so hard and thick that the ice bore horses and sleighs as far down as Watson's Point, and on the following day to the mouth of the stream. It did not break up until the latter part of the following March. The sloop Warren, lying at the wharf in Thomaston and loading with a cargo for the West Indies, was frozen in and compelled to remain there all through the winter. By the twentieth of November, the harbor of Salem, Mass., was frozen over as far out as Naugus Head; and the Connecticut river was congealed so quickly that, at Middletown in that state, within twenty-four hours after boats passed over it the ice had become strong enough to bear heavy weights and people were driving on it with their horses and sleighs. Frozen into the river were between thirty and forty vessels that had been prepared for their voyages, the masters expecting to sail before the river was closed by ice. The month of December was unusually severe, and snow storms came frequently and terrifically, great quantities of snow covering the earth to a depth that impeded travel in all portions of the country. The remainder of the winter was also severe, and in the vicinity of Rockland, Me., snow remained on the ground as late as April 10, so deep and hard-crusted that teams passed over the fences in every direction without obstruction.

Understanding the historical frequency, duration, and spatial extent of drought also assists planners in determining the likelihood and potential severity of future droughts. The characteristics of past droughts provide benchmarks for projecting similar conditions into the future.

Roll clouds and shelf clouds are the two types of arcus clouds, slight variations in their generation and look being the difference.

This application attempts to provide verification statistics for these polygon warnings. One of the motivations for polygons is to provide more accurate warnings to the public. This accuracy should be reflected in higher verification numbers.

CoCoRaHS is an acronym for the Community Collaborative Rain, Hail and Snow Network. CoCoRaHS is a unique, non-profit, community-based network of volunteers of all ages and backgrounds working together to measure and map precipitation (rain, hail and snow). By using low-cost measurement tools, stressing training and education, and utilizing an interactive Web-site, our aim is to provide the highest quality data for natural resource, education and research applications.
