National Weather Service Reference Guide
National Weather Service Reference Guide Purpose of this Document he National Weather Service (NWS) provides many products and services which can be T used by other governmental agencies, Tribal Nations, the private sector, the public and the global community. The data and services provided by the NWS are designed to fulfill us- ers’ needs and provide valuable information in the areas of weather, hydrology and climate. In addition, the NWS has numerous partnerships with private and other government entities. These partnerships help facilitate the mission of the NWS, which is to protect life and prop- erty and enhance the national economy. This document is intended to serve as a reference guide and information manual of the products and services provided by the NWS on a na- tional basis. Editor’s note: Throughout this document, the term ―county‖ will be used to represent counties, parishes, and boroughs. Similarly, ―county warning area‖ will be used to represent the area of responsibility of all of- fices. The local forecast office at Buffalo, New York, January, 1899.

Hurricane Knowledge
Hurricane Knowledge Storm conditions can vary on the intensity, size and even the angle which the tropical cyclone approaches your area, so it is vital you understand what the forecasters and news reporters are telling you. Tropical Depressions are cyclones with winds of 38 mph. Tropical Storms vary in wind speeds from 39-73 mph while Hurricanes have winds 74 mph and greater. Typically, the upper right quadrant of the storm (the center wrapping around the eye) is the most intense portion of the storm. The greatest threats are damaging winds, storm surge and flooding. This is in part why Hurricane Katrina was so catastrophic when bringing up to 28-foot storm surges onto the Louisiana and Mississippi coastlines. A Tropical Storm Watch is when tropical storm conditions are possible in the area. A Hurricane Watch is when hurricane conditions are possible in the area. Watches are issued 48 hours in advance of the anticipated onset of tropical storm force winds. A Tropical Storm Warning is when tropical storm conditions are expected in the area. A Hurricane Warning is when hurricane conditions are expected in the area. Warnings are issued 36 hours in advance of tropical storm force winds. Here are a few more terms used when discussing hurricanes: Eye: Clear, sometimes well-defined center of the storm with calmer conditions. Eye Wall: Surrounding the eye, contains some of the most severe weather of the storm with the highest wind speed and largest precipitation. Rain Bands: Bands coming off the cyclone that produce severe weather conditions such as heavy rain, wind and tornadoes. -

A Publication of the Albuquerque National Weather Service Office A Publication of the Albuquerque National Weather Service Office Whew! What a year it has been! In the wake of an eventful spring and summer, the staff members at the Albuquerque National Weather Service continue to assess reports, tally statistics, and recap the cornucopia of adverse weather epi- sodes that plagued many parts of New Mexico. In fact, the Weather Forecast Office in Albuquerque has issued a total of 501 severe thunderstorm warnings, 64 flash flood warnings, and 35 tornado warnings since January 1st, keeping a near- continuous buzz of activity over our operations center! Forecasting the weather for northern and central New Mexico certainly has its challenges, trying to pinpoint tempera- tures, precipitation, and weather hazards across a vast and diverse landscape. The highly variable topography and the numerous coincident microclimates will always demand attentive analysis, and our staff at the Albuquerque National Weather Service takes pride in providing a continuous weather watch for the residents and visitors of northern and cen- tral Mexico. Our service takes on many forms: releasing weather balloons, draft- ing a seven day forecast, issuing a winter storm warning, or even chatting on social media about the latest information on “La Niña.” No matter the avenue, we are proud to serve you, and we thank you for reading our newsletter. Inside this edi- tion, you will find a glimpse of what we are currently working on, as well as some of the latest announcements and changes that are underway at the Albuquerque Weather Forecast Office. -

SKYWARN Detailed Documentation
SKYWARN Detailed Documentation NWS Terminology Convective Outlook Categories Risk Description 0 - Delineates, to the right of a line, where a 10% or greater probability of General thunderstorms is forecast during the valid period. 1 - An area of severe storms of either limited organization and longevity, or very low Marginal coverage and marginal intensity. An area of organized severe storms, which is not widespread in coverage with 2 - Slight varying levels of intensity. 3 - An area of greater (relative to Slight risk) severe storm coverage with varying Enhanced levels of intensity. An area where widespread severe weather with several tornadoes and/or numerous 4 - severe thunderstorms is likely, some of which should be intense. This risk is Moderate usually reserved for days with several supercells producing intense tornadoes and/or very large hail, or an intense squall line with widespread damaging winds. An area where a severe weather outbreak is expected from either numerous intense and long-tracked tornadoes or a long-lived derecho-producing thunderstorm complex that produces hurricane-force wind gusts and widespread damage. This 5 - High risk is reserved for when high confidence exists in widespread coverage of severe weather with embedded instances of extreme severe (i.e., violent tornadoes or very damaging convective wind events). Hazardous Weather Risks Risk Description An advisory is issued when a hazardous weather or hydrologic event is occurring, imminent, or likely. Advisories are for "less serious" conditions than warnings that may cause significant inconvenience, and if caution is not exercised could lead to Advisory situations that may threaten life or property. The National Weather Service may activate weather spotters in areas affected by advisories to help them better track and analyze the event. -

Programming NOAA Weather Radio
Why Do I Need a NOAA Weather Radio? ⦿ NOAA Weather Radio is an "All Hazards" radio network, making it your single source for comprehensive weather and emergency information. ⦿ One of the quickest and most reliable way to get life saving weather and emergency alerts from government and public safety officials. ⦿ NWR is provided as a public service by the National Oceanic and Atmospheric Administration (NOAA), part of the Department of Commerce. What Features Do Weather Radios Have? ⦿ Tone alarm ⦿ S.A.M.E. Technology ⦿ Selectable alerting of events ⦿ Battery backup ● In the event of a power outage the radio will still work with the batteries ⦿ External antenna jack ⦿ Can be hooked up to attention getting devices ● Strobe lights, pagers, bed shakers, computers, text printers Where Should They Be Kept? ⦿ Near a window in a home or office. ● Receive better reception ⦿ It is a good idea to keep one with sports equipment for emergency alerts. ⦿ Everyone should take one with them while outdoors (boating, camping) or traveling.
