Description:
Abstract:
Transcribed Weather Enroute Broadcast (TWEB) anchor points are used to describe TWEB routes for TWEB text products for the contiguous U.S.
Purpose:
To allow Weather Forecast Offices to issue TWEB route forecasts/products. This route line shapefile and the anchor point point shapefile comprise a complete data set of TWEB routes and nodes.
Supplemental_Information:
More information about TWEBs can be found at <http://aviationweather.noaa.gov/awc/help/about_twebs.html>.
