Tropical Rainfall Continues from the Remnants of Imelda

Intense tropical rainfall continues in portions of Southeast Texas and Southwest Louisiana from the remnants of Imelda. These additional rains will only compound ongoing issues with flooding. The heavy rain focus will gradually shift to the ArkLaTex region on Friday. Also on Friday, a cold front arriving into the Upper Midwest will likely produce severe thunderstorms and locally heavy rainfall. Read More >

To reduce operations and maintenance the evaluation website at https://forecast-v3.weather.gov will be disabled until further notice beginning on 10/1/2019. An updated Service Change Notice will be sent when a new date has been determined.

The following information covers the new version of the forecast web services in development. To report real-time, operational concerns about the current version, contact the NWS Telecommunications Center (TOC) at 301-713-0902 or email TOC.NWSTG@noaa.gov. For program or general information questions, email sdb.support@noaa.gov.

Using the web site

How do I print the forecast?

All pages are now designed to be print-friendly. Click the print button in your browser for a presentation that is environmentally friendly to print.

Can I embed the forecast on my web page?

Yes. You can also customize the appearance of this forecast using the mode parameter. There currently three modes: min, widget, and ext.

  • The min mode will only display the basic components: header, navigation, and detailed forecast.
  • The ext mode will display the header, navigation, and the extended forecast.
  • The widget mode will display the observation, extended forecast, and detailed forecast, but removes the header/footer(a common request when using an HTML iframe).

Example: https://forecast-v3.weather.gov/point/38.9588,-94.624?mode=min.

A future version of the forecast page will provide a JavaScript library that will place the forecast onto your site without an iframe.

Why is the zone page showing on the forecast page?

The forecast will redirect to a zone page when there was is a technical issue with the forecast page, indicated by a blue banner with the message, "The zone data will be displayed until your location has been refreshed." This condition can occur when the forecast page cannot process the data provided by the field office or the data has expired. The field offices work quickly to issue updated data, and you do not need to submit a support ticket unless you experience this issue for a prolonged period of time.

Why is the forecast not using the closest observation station?

If the closest observation station does not have a current observation then the forecast page will use the next closest observation station. The list of observations stations is determined by the field office responsible for the forecast. Please use the contact information in the footer of the forecast page to contact the field office concerning observation issues.

Known Issues

Web Site

  • Forecast page incorrectly displays a hazard condition (also known as an alert) that was updated or corrected. When a the status of a hazard condition is updated the API might be delayed in reflecting the status change on the forecast page. This is a known issue with the alert data sent by the NWS Telecommunications Operations Center, and will be resolved in a future update.

    Tracking code: 847

  • The forecast hourly weather graph and hourly weather table does not provide bookmarking to retain selected options. This feature will be added to the web site on a future update.

    Tracking code: 826

  • The forecast page does not redirect locations in Canada to Environment Canada's weather site. The forecast page now displays a user-friendly error page indicating the location is not within the the NWS boundaries. The redirect will be revisited for a future update.

    Tracking code: 896

  • Older versions of Firefox may have presentation inconsistancies. Specific examples include the display of the time (e.g. "NOW until...") for hazard shading on conditions currently in affect, and the forecast page mini map might retain the view of the entire US versus automatically zooming to the appropriate point or zone.

API

Please refer to the "Issues/Changes" tab on the API page for issues that impact alert endpoints.

Change Log

Web Site

No changes.

API

No changes.

The forecast pages have been rewritten to modernize the structure, remove duplications, and provide a service-oriented data structure or API. Developers using the NWS API will need to update their application to reflect the new version. It has been improved to provide richer data sets through linked data to other resources. Please refer to the API Web Service documentation for more details.

What will change on the web site?

The user experience remains mostly the same, as the primary goal of this update is to provide more consistent service. The URLs of many pages will change, including all forecast pages, and this will break existing bookmarks that users may have. A link on the error message of the old page will guide users to the new location. Users can now select a location on a mobile device, and the hourly weather was added to the mobile site.

What happened to the text-only forecast?

The most common use of the current text-only forecast was by low-bandwidth users. This also meant low-bandwidth users missed out on basic navigation and other information. Rather than completely eliminating the information, the new version of the forecast pages will present the same information using a low-bandwidth display. The low-bandwidth display will now apply to all pages, not just the forecast. Enable this presentation by setting the "view" parameter to: plain.

Example: https://forecast-v3.weather.gov/point/38.9588,-94.624?view=plain

Also see the question "Can I embed the forecast on my web page" that will further reduce the overall page bandwidth. Note that this feature is still being optimized for best performance.

Example: https://forecast-v3.weather.gov/point/38.9588,-94.624?view=plain&mode=min

Will the web site work on my mobile device?

The web site was designed to replace mobile.weather.gov, and uses a responsive design that displays well on any device. Key features of the mobile site were transferred to the new version, including a mobile-friendly search page and the hourly forecast.

What happened to the link to the Spanish forecast?

The link is now named "Pronostico en Espanol" and is located in the "Additional Forecasts and Information" section on the forecast page.

What happened to the "Share" link to social media?

The "Share" social media links and icons were removed because of technical concerns. This feature will be revisited soon.

Where did the red, "Hazardous Weather Conditions" box on the forecast page go?

All warnings are now contained within the extended forecast section on the forecast page, and are limited to the NWS watches, warnings, advisories, and other similar products in the Common Alerting Protocol (CAP) version 1.2. Please refer to the CAP 1.2 service change notice for more details.

What if I experience an issue with the web site?

Please review the "Known Issues" tab on this page and contact us if the problem is not already identified.
