For example, deployments of the Weather Surveillance Radar-1988 Doppler (WSR-88D) network, geostationary- and polar-orbiting satellites, advanced data assimilation techniques and fine- resolution models on high-performance computers, and the Advanced Weather Interactive Processing System (AWIPS) have led to an increase in the yearly national average tornado warning lead time from 3 minutes in 1979 to 12 minutes in 2002, an increase in the yearly national average flash flood warning lead time from 8 minutes in 1987 to 53 minutes in 2002, and a decrease in the yearly average 72-hour hurricane track Infusing new science and technology has improved national forecast error from 450 nautical miles in 1970 to 190 average tornado warning lead times (minutes). nautical miles in 2002.

  • Watches and Warnings
    Watches and Warnings... The National Weather Service sees the potential for severe weather, and a stream of weather information flows from our forecast offices to you. Each National Weather Service forecast office has a web site, a Facebook page, and a Twitter feed where you can find vital Information highlighting upcoming weather hazards. The hazardous weather outlook, a text product, highlights weather hazards seven days in advance. The Storm Prediction Center in Norman Oklahoma also forecasts the risk for severe weather across the country several days in advance. These outlooks will tell you if there is a risk for severe weather, and if you are in a marginal, slight, enhanced slight, moderate, or high risk area for severe weather. If severe weather becomes likely within six hours, a watch will be issued, alerting you to the increased risk for severe weather. If you are in or close to the watch area, you should plan where to go for shelter if severe weather occurs. If high wind is a threat, tying down or bringing loose objects indoors would be a wise move. If large hail is a threat, protecting your vehicle would be a good idea. Then, forecasters at the local National Weather Service forecast office will monitor satellite and radar data, and collaborate with severe weather spotters. Forecasters will issue warnings to alert you of the imminent severe weather threat. The warnings are sent out in many different ways in order to reach the most people possible. A warning is an urgent message telling you that severe weather or flooding is imminent or is occurring.

  • Clean Air Blue Skies July 2015
    Clean Air Blue Skies July 2015 Pinal County Travel Reduction Clean Air Blue Skies Pull Aside Stay Alive Warning Information for Monsoon Season Armed with Doppler radars, powerful su- percomputers, advanced weather satel- lites, automated weather and stream gag- es, and an advanced lightning detection network, forecasters at the National Weather Service are able to provide high- ly accurate severe weather warnings. Advanced National Weather Service com- puter systems now allow warnings to be generated in seconds for highly detailed areas. Those warnings are then transmit- ted to the public, the media and emergen- cy management officials via NOAA Weather Radio, The Emergency Alert System, and the Internet. Television meteorologists play critical roles in the warning process. They relay National Weather Service warnings to the public and provide additional details about the storms, what they are doing and where they are going. Weather Terminology Watches mean that widespread severe weather is possible. A watch means that severe weather has not occurred yet, but weather conditions are becoming highly volatile. Pay close attention to the weather, and tune into TV, radio, or NOAA Weather Radio broadcasts frequently. Warnings (Severe Thunderstorm, Flash Flood, Dust Storm, or in rare cases, Tornado) mean that life-threatening weather is about to occur, or has been reported. Take action immediately. Flood Advisories mean heavy rains will cause minor flooding of washes, streams, and typical flood-prone areas. Flood- ing in this situation is usually not serious. If the flooding does become life threatening, then the flood advisory is upgrad- ed to a Flash Flood Warning. 2 Clean Air Blue Skies UK’s first “poo bus” went into regular service Britain’s first “poo bus”, which runs on human and household waste, went into regular ser- vice in March 2015.

    Product/Service Description Document Consolidation and/or Reformatting of Flooding Products Updated May 2021 Part I - Mission Connection a. Product/Service Description – The National Weather Service may begin to implement the consolidation (i.e. reduction in the number of) and/or reformatting (i.e. simplified product text) of Flood Watches, Warnings and Advisories (WWA) beginning on or after September 8, 2021. ● First, Flash Flood Watches and Flood Watches will be consolidated into one Flood Watch product when the immediate cause is excessive rainfall. Flash Flood Watches will be maintained for these specific situations only: ○ Possibility of flash flooding due to non-convective causes (e.g., dam or levee failure, ice jam) ○ Possibility of flash flooding and debris flows caused by excessive rainfall on burn scars or in debris flow- and landslide-prone areas. ● Second, the five types of individual headlines associated with Flood Advisory products, including Urban and Small Stream Flood Advisories, Arroyo and Small Stream Flood Advisories, Small Stream Flood Advisories, Flood Advisories, and Hydrologic Advisories, will be consolidated to Flood Advisory. ● Third, the Flood Watch, Flood Watch for Forecast Points, Flash Flood Watch, Flood Warning, Flood Warning for Forecast Points, Flood Advisory, and Flood Advisory for Forecast Points will be reformatted into “What”, “Where”, “When”, “Impacts”, “Additional Details” information ordering format. The Flash Flood Warning and Flash Flood Statement will remain in Impact-Based Warning (IBW) format as described in the Product Description Document (PDD) at the link below: https://nws.weather.gov/products/PDD/IBWforFlashFloods_2019.pdf.
