Table 1 shows precipitation and temperature ranks for each of the 9 regions and the nation for the Winter Season 1998-99. Note: the Statewide Rank Maps are presented on the Statewide Analyses page.
TABLE 1. TEMPERATURE AND PRECIPITATION RANKINGS FOR DEC 1998-
FEB 1999, BASED ON THE PERIOD 1895-96 TO 1998-99.
1 = DRIEST/COLDEST, 104 = WETTEST/HOTTEST.

It should be emphasized that all of the temperature and precipitation ranks in Table 1 are based on preliminary data. The ranks will change when the final data are processed.
Table 2 shows historical extremes for Winter, the 1961-1990 normal, and the Winter 1998-99 value for each of the 9 regions and the contiguous U.S. for precipitation and temperature.

The preliminary temperature and precipitation rankings are available from the center by calling: 828-271-4800 or on the World Wide Web here. Historical precipitation and temperature ranking maps are also available on the Internet at: http://nic.fb4.noaa.gov/products/analysis_monitoring/regional_monitoring/usa.html. NOAA works closely with the academic and science communities on climate-related research projects to increase the understanding of El Niño and improve forecasting techniques. NOAA's Climate Prediction Center monitors, analyzes and predicts climate events ranging from weeks to seasons for the nation. NOAA also operates the network of data buoys and satellites that provide vital information about the ocean waters, and initiates research projects to improve future climate forecasts. The long lead climate outlooks are available on the Internet at: http://nic.fb4.noaa.gov.
