Currently on an experimental basis, the National Weather Service in Birmingham has developed this GIS data page in an effort to share meteorological geospatial information to the public and GIS analysts.  This page is intended to be a one stop shop portal for access to GIS information that has been published in the past, as well as the latest information.  Our goal is to offer meteorological data to the most savvy GIS analysts as well as folks just beginning to learn about GIS.  We have tried our best, therefore, to offer data in multiple geospatial formats.  ESRI Shapefiles are offered for GIS analysts and agencies looking to create their own maps in ArcGIS and perform spatial modeling and analysis. Google Earth KMZ files are offered for those who want a detailed interactive view of GIS data.  Finally, interactive web maps are available for those that don't have GIS software installed on their PC, but would still like to view detailed GIS information from the convenience of their web browser.

NOTE:  For quick access back to this page, you can use the quick link on the left-hand menu under "Additional Info" and click on "GIS Information."

Have questions or comments about these data?  We'd love to hear from you!  Send your thoughts to our Webmaster and we will have our GIS Focal Point contact you directly.  The more comments and suggestions that we receive from our customers will help to improve GIS data across the entire National Weather Service.

What is a GIS?

A Geographic Information System (GIS) integrates hardware, software, and data for capturing, managing, analyzing, and displaying all forms of geographically referenced information.

GIS allows us to view, understand, question, interpret, and visualize data in many ways that reveal relationships, patterns, and trends in the form of maps, globes, reports, and charts.

Damage Assessment Toolkit Data
Damage Assessment Toolkit Info
Storm Survey Information Gathered Utilizing the Damage Assessment Toolkit
Following a tornadic severe weather event across Central Alabama, assessment teams are dispatched to investigate damage along a specific tornado path.  Survey crews are then able to gather GIS information in the form of survey points utilizing mobile technologies.  These data offer detailed and comprehensive survey information that are able to be sent to a centralized GIS server.  We can then extract the data into a usable format utilizing the National Weather Service Damage Assessment Toolkit.  The toolkit has been developed by National Weather Service Meteorologists to help modernize storm survey information into a geospatial format for the general public and GIS analysts.  The information can be passed along to decision makers and the emergency management community after storm surveys have been completed to help aid cleanup and recovery efforts.  The Damage Assessment Toolkit will continue to be devloped and improved, and is currently well on its way to being utilized by National Weather Service offices throughout the United States.  Be advised that all information available for download is subject to change, and is considered experimental.

NWS Birmingham Tornadic Event GIS Info:

Each linked date below denotes the specific day that a tornadic severe weather event occurred in Central Alabama throughout a given year.  The links will take you directly to the GIS data page of interest, where individual ESRI Shapefiles or Google Earth KMZ files can be conveniently downloaded.  Interactive tornado track web maps are also available on select pages.  Damage Assessment Toolkit data are currently available from the April 15, 2011 Tornado Outbreak to present. Select a year below to view specific dates that GIS data are available.

The National Weather Service in Birmingham is now offering Local Flood Inundation Maps for select locations across Central Alabama.  These Flood Inundation Maps show the extent of flooding expected spatially over a given area. The maps also indicate where roadways, streets, buildings, etc., are likely to be impacted by floodwaters. The easily accessible map graphics provide users more awareness of the flood hazards in their local area. Combined with river observations and NWS river forecasts, the goal of these inundation maps is to provide decision-makers additional information needed to better mitigate the impacts of flooding and build more a resilient community.

Be advised that all flood information available is considered as an estimate and is experimental.


 Local Flood Inundation Maps:

Each link below will take you to the flood inundation maps of interest.  Interactive maps will allow you to view down to street level where flood impacts could be felt based on creek and river levels rising to specific elevations due to heavy rainfall either upstream or at the specific location. Once again, the flood information is considered an estimate and is experimental.
