Subject: Termination of the Day 3-7 Hemispheric Charts:
Effective July 24, 2024

Effective on July 24, 2024, the National Weather Service (NWS)
will terminate the Day 3-7 Hemispheric Charts (hemispheric
graphic products for each of days 3-7).  These charts are
graphical products that depict the locations of surface fronts
and pressures over a portion of the Northern Hemisphere.

The NWS will continue to produce similar forecast charts for
domains centered over the contiguous United States (CONUS) and
Alaska with no additional change in service.

The Day 3-7 CONUS charts are available at:
https://www.wpc.ncep.noaa.gov/medr/medr.shtml

The Day 4-8 Alaska charts are available at:
https://www.wpc.ncep.noaa.gov/alaska/akmedr.shtml

This change has been coordinated to ensure that the charts
depicting the forecasts of fronts and pressure systems will
continue for the CONUS and Alaska domains on the Aviation
Weather Center`s interactive Prog Chart Viewer:
https://aviationweather.gov/gfa/#progchart

Additionally, the Ocean Prediction Center currently produces
forecast charts for three domains over the Arctic/Alaska,
Pacific Ocean, and Atlantic Ocean through Day 4, with a Day 5
forecast for major low pressures included on the Day 4 chart
with an arrow and an X depicting the forecast Day 5 location.
These charts are available at the following URLs:
https://ocean.weather.gov/AK_tab.php
https://ocean.weather.gov/Pac_tab.php
https://ocean.weather.gov/Atl_tab.php
