General Information - Road-Weather Transactions (HQ/HR)
An agency may request out-of-state road and weather information by sending an inquiry (HQ) through Nlets to a participating state. A road/weather information file will be maintained by each participating state. Inquiries and responses are exchanged via Nlets similar to the way motor vehicle inquiries and responses are exchanged.
The NOAA weather wire services (NWWS) are now transmitted to the states via the Nlets network. This allows states to select between various weather data options that affect their state.
The states participating in the Nlets Road/Weather Program may be obtained by sending an Administrative Message (AM) to the ORI "NLWTHHELP".
Should Nlets users choose to send weather inquiries to any of the states listed as not participating, they should not expect a response of any kind. This does not preclude requesting weather conditions for a specific community or area using an administrative (AM) message.
You can reach the IDP support team at NCEP via email at idp-support@noaa.gov or nco.ops@noaa.gov, or call (301) 683 1518 during normal business hours. To contact the Senior Duty Meteorologist you can send an email to sdm@noaa.gov or call (301-683-1500).
Query Requirements
- Up to 5 two character state codes are permitted per inquiry.
- At the present time there is no fixed response.
- If a state is unable to support automated responses, manual responses are acceptable.
IMPORTANT NOTE: Each state's road/weather file must contain enough information and must be
updated often enough to be meaningful.
- Road/weather inquiries do not have to be in a fixed format except for the time and date fields preceding the text information in an inquiry and the "TIM/" and "DAT/" field following the "TXT" in a response.
Should a state choose not to support road/weather inquiry, a standard response should be returned.
