Metropolitan Weather Hazards Protection Act of 2015

To require the Secretary of Commerce to maintain and operate at least one Doppler weather radar site within 55 miles of each city in the United States that has a population of more than 700,000 individuals, and for other purposes. 1. Short title This Act may be cited as the Metropolitan Weather Hazards Protection Act of 2015 2. Requirement for operation of Doppler weather radar sites near large cities (a) Requirement Beginning not later than 450 days after the date of the enactment of this Act, the Secretary of Commerce shall— (1) maintain and operate at least one Doppler weather radar site within 55 miles of each city in the United States that has a population of more than 700,000 individuals; and (2) ensure that each radar maintained and operated near a city described in paragraph (1) is available to the office of the National Weather Service that provides services to such city. (b) Standards The Secretary shall ensure that each radar maintained and operated under subsection (a) conforms with the same standards that apply to radars operated by the Secretary, acting through the Administrator of the National Oceanic and Atmospheric Administration, on the day before the date of the enactment of this Act, including standards relating to the use of dual-polarization technology or other technologies included in Weather Surveillance Radar, 1988, Doppler (WSR–88D) radars. (c) Considerations When determining the location for constructing a radar to meet the requirements of subsection (a), the Secretary shall take into consideration nearby counties that have populations of more than 130,000 and do not otherwise have radar beam coverage below 10,000 feet from Weather Surveillance Radar, 1988, Doppler (WSR–88D) radars. (d) Report (1) In general Not later than 180 days after the date of the enactment of this Act, the Secretary shall submit to Congress a report detailing the Doppler weather radar sites that need to be constructed or acquired in order to meet the requirement of subsection (a). (2) Contents The report submitted under paragraph (1) shall include the following: (A) Feasible locations for placement and construction of radar sites, determined by the Secretary to provide the necessary meteorological capabilities to best protect a city described in subsection (a). (B) A timeline for when construction or acquisition of each radar site will be complete.

Summary: (Sec. 1) This bill directs the Department of Commerce to complete, within 90 days after enactment of this bill, a study on gaps in the coverage of the Next Generation Weather Radar of the National Weather Service (NEXRAD). In conducting this study, Commerce shall identify areas in the United States with limited or no NEXRAD coverage below 6,000 feet above ground level of the surrounding terrain. For those areas identified, Commerce shall also: identify the key weather effects for which prediction would improve with improved radar detection; identify additional sources of observations for high impact weather available and operational for such areas, including Terminal Doppler Weather Radar, air surveillance radars of the Federal Aviation Administration (FAA), and cooperative network observers; and assess the feasibility and advisability of efforts to integrate and upgrade federal radar capabilities in such areas that are not owned or controlled by the National Oceanic and Atmospheric Administration, including radar capabilities of the FAA and the Department of Defense. In addition, under such study Commerce shall: assess the feasibility and advisability of incorporating state-operated and other nonfederal radars into the operations of the National Weather Service; identify options to improve radar coverage in all of the areas identified as having limited or no NEXRAD coverage; and estimate the cost of, and develop a timeline for, carrying out each of the options identified. After completing the study, Commerce shall submit a plan for improving radar coverage in the identified areas by integrating and upgrading, where practicable, additional observation solutions to improve hazardous weather detection and forecasting. Commerce shall seek third-party reviews on scientific methodology related to, and the feasibility and advisability of, implementing the plan to improve radar coverage, including the extent to which warning and forecast services of the National Weather Service would be improved by additional NEXRAD coverage.
