Tornado Warnings are issued to enable the public to get out of harm’s way and mitigate preventable loss. NWS forecasters issue approximately 2,900 Tornado Warnings per year, primarily between the Rockies and Appalachian Mountains. Tornado Warning statistics are based on a comparison of warnings issued and weather spotter observations of tornadoes and/or storm damage surveys from Weather Forecast Offices in the United States. Lead Time (LT) for a Tornado Warning is the difference between the time the warning was issued and the time the tornado occurred (based on certified reports) in minutes, assuming the tornado tracked within the bounds of the warned area. Lead Times for all tornado occurrences within the U.S. are averaged to get this statistic for a given fiscal year. This average includes all warned events with zero lead times and all unwarned events. Lead Time is calculated down to the minute for individual Tornado Warnings and tornadic events. Although the timing of the warning transmission is recorded to the nearest second, typically there is only an estimate to the nearest minute of when a tornado touches down. Additionally, even though we can compute the average tornado warning lead time to a precision of 30 second increments or less, the reporting of this value implies greater accuracy in the data based on scientific and logistical restrictions on tornado reporting and surveying. Most tornadoes cannot be visually tracked from beginning to end and post-storm damage surveying is the official method with which the NWS categorizes tornado characteristics (intensity, path length & width) but must rely on radar data to estimate the timing of the tornado track.

Tornado Warnings are issued to enable the public to get out of harm’s way and mitigate preventable loss. NWS forecasters issue approximately 2,900 Tornado Warnings per year, primarily between the Rockies and Appalachian Mountains. Tornado Warning statistics are based on a comparison of warnings issued and weather spotter observations of tornadoes and/or storm damage surveys from Weather Forecast Offices in the United States. The false alarm ratio (FAR) is the percentage of times a tornado warning was issued, but no tornado occurrence was verified. Most tornadoes cannot be visually tracked from beginning to end and post-storm damage surveying is the official method with which the NWS categorizes tornado characteristics (intensity, path length & width) but must rely on radar data to estimate the timing of the tornado track.

*Please also note that a FAR is the number of false alarms per the total number of warnings. If an FAR actual is higher than the target, then the target has not been met. If the actual is the same number or less, then it has been met or exceeded.

In May 2019, the SI will be redefined with units based on fundamental constants of nature. NIST’s role in this transition from a classical to a quantum definition will be one of leadership. NIST will explore the foundational limits of the Quantum SI by integrating efforts in fundamental research, applied research and dissemination of the SI units. NIST’s goal is to develop Quantum SI standards and sensors for mainstream US industry, and disruptively change the classical dissemination modality

Cumulative number of R2X projects that include social science research and methods to address forecaster and end user needs to prepare for and respond to/ minimize societal impact for extreme weather events.

Ensures that NOAA safely archives critical data and information according to National Archives and Records Administration (NARA) standards.

Metric calculated as the percent of Climate Prediction Center extended (outlooks out to 14 days) and long range (monthly and seasonal outlooks) temperature and precipitation outlooks exceeding Heidke Skill Score (HSS) of 10 (10% better than a climatological forecast). Due to the scarcity of long range outlooks (six per month), scores are smoothed over a three year period. To better track results, three individual metrics are tracked – 1) All forecasts combined, 2) Temperature only, and 3) Precipitation only.

The flash flood warning accuracy (probability of detection for storm-based warnings) represents the percentage, in both space and time, for which a flash flood event was warned. Historically, flash flood warnings were issued and verified on a countywide basis. Starting in FY 2010, the storm-based warnings were implemented with verification based solely for the areas impacted by the warning and event.

This indicator seeks to demonstrate that use of the Cybersecurity Framework is increasing, and that guidance and other tools are being developed and made publicly available to help organizations use the Framework to understand, manage, and communicate cybersecurity risk. Cybersecurity Framework resources may be developed by any organization, including industry, academia, government, and nongovernment organizations. These resources may include, but are not limited to, implementation guides, mappings, case studies, educational materials, example profiles, etc.

NOAA is consolidating activities for the NAVSTA Newport, RI location. Currently NOAA has two ships homeported at NAVSTA, the Henry B. Bigelow and Okeanos Explorer. In order to remain in compliance with the CENOTE Act, NOAA is required to co-locate with the Navy whenever possible to increase technological sharing capabilities. This consolidation aligns with NOAA's regional facilities plans. The OMAO consolidation has milestones to complete design (FY22), and then FY23 issuance of an RFP and award of the contract.
