ATTENTION: ALL NWS EMPLOYEES, FAMILY OF SERVICES SUBSCRIBERS,

***** NOTICE *****
The Automated Surface Observing System (ASOS) at Sexton Summit,
Oregon (call letters SXT) will be commissioned by the National
Weather Service on December 31, 1992. Commissioning of Sexton
Summit means that ASOS will replace the MANUAL surface aviation
observation currently being taken at these locations with an
AUTOMATED surface aviation observation. Commissioning of this
ASOS will expand surface observations from 9 per day, 5 days-per-
week to a 24-hour, seven-day-per-week operation. NOTE: Because
ASOS observational formats are different from manual
observational formats, automated decoder programs may require
software modifications. Persons wishing more information
concerning ASOS should contact their local National Weather
Service office or call (301) 713-1781, FAX (301) 713-0003.

1992: WEATHER IN ITS EXTREMES
The weather in 1992 was notable in its extremes, but well within the expected range of weather and climate variations, according to meteorologists at the National Oceanic and Atmospheric Administration's National Meteorological Center. Ron McPherson, Director, National Meteorological Center, and NOAA climate researchers, characterized the most "notable" climate events over North America in their annual weather wrap-up. The year brought continued drought in the Far West; a very mild winter (1991-92) in southwest Canada and the northwest and north central United States; a cool, wet summer and growing season (1992) in the central and eastern portions of Canada and the U.S.; and severe storms with record setting devastation across the nation. Long term drought in the Far West, considered by some experts to be a once in 400-year event, is now entering its seventh consecutive year in some places. Although southern sections of California recorded surplus winter-time precipitation, drought continued to adversely affect California's water storage. Nearly all of the state's reservoirs are located in the north, and most of this area received less than 75-percent of its normal November-March precipitation. Forest fire potential increased in several western states. NOAA Climatologists noted that the recent El Nino (1991-92)--a warming of South Pacific waters-- and the eruption of Mt. Pinatubo (June 1991), with its global distribution of volcanic particles high in the atmosphere, may have played some role in the year'swinter and summer temperature anomalies.
A large portion of North America experienced winter temperatures which averaged between four and thirteen degrees Fahrenheit above normal, making the winter of '92 the warmest on record nationally (since records began in 1895) and the third consecutive December-March with national temperatures above the long-term average. Spring-Summer (April through November) temperatures averaged from
one to four degrees Fahrenheit below normal across the eastern two thirds of the U.S. and Canada. Despite temperatures much above normal in the Far West, the eight month average for the entire U.S.ranked as the 20th coldest such period since 1895. The mild winter and cool summer helped reduce natural gas usage and
electric power demand officials said. The nation's gas home heating customers spent about $1.5-billion less than expected for heating during the 1991/92 heating season. The 1992 Atlantic Hurricane season was below normal with six named storms, four reaching hurricane intensity. The late starting season developed a small, but brutal, Hurricane Andrew which devastatedparts of the Bahamas, South Florida, and Louisiana in late August. Andrew was the third most intense hurricane to make landfall this
century and the most destructive natural disaster in the nation's history. Andrew took 59 lives, destroyed 61,000 homes, damaged 75,000 others and left 250,000 people homeless according to the National Association of Independent Insurers. The eastern Pacific storm season was a record breaker with 27 tropical cyclones and 24 named storms. The National Weather Service exhausted its list of storm nicknames prompting theannouncement of a back-up contingency, the Greek alphabet.
Tornado activity was at near record levels over the United States for the third consecutive year. Preliminary numbers show as many as 1,300 tornadoes reported across the nation. Despite this unusually high number for the year, there were 38 tornado-related deaths,about half the average for the last 20 years.
Two record hailstorms pounded central Florida during March. A hail storm with hail "drifts" a foot deep in southern Seminole County caused $25-million dollars in damage. A second storm with hail stones as large as grapefruit and softballs produced $60-million dollars in damage. NOAA climate analysts say the weather outlook for this winter (January through March, 1993) is for above normal temperatures (55 percent probability) from Lake Superior across the northern Great Plains and Intermountain region to the Oregon coast. The northwest, and western sections of Nevada and Arizona, should expect above normal temperatures. There is a 65-percent chance for extra warmth over northwestern Minnesota, the extreme northern Great Plains andfor central and northern California.
There is a 55-percent chance of below normal winter temperatures in an area south and east of a line running from west-central Texas across the middle Mississippi Valley to the eastern Great Lakes and northern New England, except Maine. Within this area forecasters say there is at least a 70-percent chance for sub-normal temperatures in Georgia and at least a 75-percent over the southern Appalachian region. Elsewhere temperature forecast probabilities do not depart significantly from seasonal norms. Below median precipitation is forecast for the northern Rockies and Central Intermoutain Region and western sections of the northern Great Plains, the upper and middle Mississippi Valley, the Great Lakes Region, the Ohio Valley and Tennessee. There is a 60-percent chance for below median precipitation over Illinois, Indiana and southwestern Michigan. Above median amounts of precipitation are expected (55-percent probability) over southern sections of New Mexico and Texas and much of Florida. Elsewhere precipitation amounts do not depart significantly from seasonal norms. SENT - W/OM23 END NNNN
