Proposal to operationally implement the Hurricane Local Watch/Warning Product (TCV) at WFO Honolulu The Hurricane Local Watch/Warning product (TCV) was operationally implemented at Weather Forecast Offices (WFOs) in the Atlantic hurricane basin during the 2015 Hurricane season to accompany changes made to the Hurricane Local Statement. Plans to implement for Western Region and the remainder of Pacific Region are to be determined at a later date. For the 2017 Hurricane Season, WFO Honolulu plans to begin issuing the TCV in the same format used by the WFOs covering the Atlantic Hurricane Basin. There will be no changes for Western Region or for other WFOs in the Pacific Region. Jessica Schauer 2016-12-06
Proposed changes to the criteria for issuing tropical cyclone watches and warnings to include certain land-threatening disturbances that are not yet tropical cyclones The National Weather Service (NWS) proposes beginning on or about May 15, 2017,to have the option to issue watches, warnings, and graphical and textual advisory products for disturbances that are not yet a tropical cyclone, but which pose the threat of bringing tropical storm or hurricane conditions to land areas within 48 hours. Under previous long standing NWS policy, the NWS has not been permitted to issue a hurricane or tropical storm watch or warning until after a tropical cyclone had formed. Jessica Schauer 2017-01-31
Proposed Changes to Tropical Cyclone Forecast Graphics and GIS Files Effective on or about May 15, 2017, the appearance of the graphics accompanying tropical cyclone advisory packages issued by the National Hurricane Center (NHC) and Central Pacific Hurricane Center (CPHC) will change. These changes are required for the NHC and CPHC to begin issuing forecasts and watches/warnings for potential tropical cyclones.three new Keyhole Markup Language (KML) files will be available and the wind speed probability Geographic Information System (GIS) files will be available at higher resolution.

Proposed changes to the Operational Collaborative Convective Forecast Product (CCFP):Traffic Flow Management Convective Forecast (TCF) The Federal Aviation Administration (FAA) has requested the National Weather Service (NWS) update the CCFP to only include high-confidence forecasts and to rename the product the Traffic Flow Management (TFM) Convective Forecast (TCF). Like the CCFP, the TCF is a NWS product collaborated by meteorologists at the Aviation Weather Center (AWC) in Kansas City and embedded at the FAA Air Traffic Control System Command Center (ATCSCC) in Warrenton, VA, at the Center Weather Service Units (CWSU) embedded at the FAA’s Air Route Traffic Control Center (ARTCC), and at various airlines and authorized organizations. The TCF is a high confidence graphical representation of forecasted convection meeting specific criteria of coverage, intensity, and echo top height. These forecasts will allow Air Traffic Management (ATM) decision makers to proactively and collaboratively initiate, amend, or terminate planned or active Traffic Flow Management initiatives, resulting in safe and efficient use of the NAS.

Proposed Changes to the National Tropical Cyclone Watch and warning (TCV) products for the Atlantic Basin for 2017 Effective on or around June 1, 2017, the National Hurricane Center (NHC) will expand the tropical cyclone watch and warning information available in its National Tropical Cyclone Watch/Warning (TCVAT#) products issued for Atlantic tropical cyclones. In past hurricane seasons, the National TCV products for the Atlantic basin contained only the tropical cyclone wind watches and warnings along coastal segments issued by NHC. Beginning in the 2017 hurricane season, the national TCV products from NHC for the Atlantic basin will include all NWS-issued zone-based tropical cyclone wind and storm surge watches and warnings from both NHC and local Weather Forecast Offices (WFOs) and will no longer contain breakpoint information.
