Look at your home on the SLOSH models. If it shows you in a flood prone area in Florida due to storm surge then I would get ready for a premium increase.
I copied this from the NFIP Site
1. What data sources is FEMA using for this initiative? Where are the data coming from?
FEMA is using a combination of models to support the development of rates. We are pairing state-of-the-art industry technology (e.g. catastrophe [CAT] models) with the NFIP’s mapping data to establish a new risk-informed rating plan. Combined data from CAT models and NFIP mapping data will provide a better and more comprehensive understanding of risk at both the national and local level.
FEMA is using data from multiple sources, such as:
- FEMA: Existing mapping data, NFIP policy and claims data;
- Other Federal Government Agencies: U.S. Geological Survey (USGS) publicly-available data;
- National Oceanic and Atmospheric Administration (NOAA) Sea, Lake, and Overhead Surges from Hurricanes (SLOSH) data;
- U.S. Army Corps of Engineers (USACE) data sets; and
- Third-party sources: Commercially-available structural and replacement cost data and catastrophe flood models.
“Risk Rating 2.0” now goes into effect Oct. 1, 2021. Rather than rely heavily on flood zones to determine policy premiums, Risk Rating 2.0 will consider more variables and charge premiums that vary by home.
