Preliminary FEMA Map Products
FEMA is making IT upgrades that will temporarily take some applications offline, including the Mapping Information Platform (MIP), the Studies Tracker Map, Electronic Letter of Map Amendment (eLOMA), Online Letter of Map Change (LOMC), Mitigation Planning Portal (MPP), Federal Geospatial Data Coordination by State (State Contacts), Status of Map Actions (SOMA), LOMA Logic, the Flood Risk Study Engineering Library (FRiSEL) and the Preliminary Product Site. These applications will be unavailable Friday, November 1 through Sunday, November 10. To access your Preliminary Flood Hazard Data, please use the Alternate Preliminary Site.

During the downtime, Letters of Map Revision that go effective between November 2 and November 10, 2019 will not appear in the National Flood Hazard Layer (NFHL) until November 11, 2019. LOMRs that go effective November 1 will appear on the NFHL before the downtime. The NFHL Viewer in the MSC Address Search will be up-to-date once again on November 11. Users may access the LOMRs during this time through the MSC's Search All Products.

Preliminary flood hazard data (preliminary data) provide the public an early look at their home or community‘s projected risk to flood hazards. Preliminary data may include: new or revised Flood Insurance Rate Maps (FIRM), Flood Insurance Study (FIS) reports, and FIRM Databases. This tool makes nation-wide preliminary data available in a centralized and easily accessible location, along with FEMA‘s other flood hazard mapping products. For more information about preliminary data, go to FEMA‘s Preliminary Flood Hazard Data webpage.
Please note, if you do not see your community‘s preliminary data, contact the FEMA Map Information eXchange (FMIX) for further support.
Disclaimer: Preliminary data are for review and guidance purposes only. By viewing preliminary data and maps, the user acknowledges that the information provided is preliminary and subject to change. Preliminary data, including new or revised FIRMs, FIS reports, and FIRM Databases, are not final and are presented on the MSC as the best information available at this time. Additionally, preliminary data cannot be used to rate flood insurance policies or enforce the Federal mandatory purchase requirement. FEMA will remove preliminary data once effective data are available.
