Albuquerque National Weather Service Fall 2017 Page 2 Page 4 Page 7 NEWSLETTER Winter Hazard Simplification 2017 Brings Barrage of Familiar faces join Rolls Out Severe Weather to NM our team! 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. -

Winter Storm Terms Winter Safety Tips
November-December 2015 ONTARIO COUNTY Volume 17 #6 I wanted to share a couple of general safety tips for the coming winter weather. Winter Storm Terms Here’s an updated list of terms used by the National Weather Service. Blizzard – sustained or gusty winds of 35 mph or more, and falling or blowing snow creates visibilities at or below ¼ mile for at least 3 hours. Blizzard Warning – a blizzard is possible and the public should seek shelter immediately as snow and strong winds could combine to produce blinding snow, near zero visibility, deep drifts and life threatening wind chill. Blowing snow - wind-driven snow that reduces visibility and will cause drifting. Blowing snow may be falling snow and/or snow on the ground picked up by the wind. Dense Fog Advisory - fog reducing visibility to ¼ mile or less over a widespread area. Freezing rain - rain with a temperature below freezing. The freezing rain will coat surfaces like trees, cars and roads forming a coating or glaze of ice. Even small accumulations could be a significant hazard. Frost-freeze advisory – temperatures below freezing expected that could damage to plants, crops, or fruit trees. Ice storms - winter storms that may include freezing rain or sleet. Lake Effect Snow Advisory – lake effect snow expected that will cause significant inconvenience. Lake Effect Snow Warning - heavy lake effect snow that is imminent or occurring. Sleet - rain that turns into frozen ice pellets before reaching the ground. It usually bounces off and does not stick to objects but can accumulate like snow and cause a hazard to motorists on roadways. -
