From the storm reports

Flash Flood · Mar 22, 2022. An upper level system moved into north-central Texas on March 22nd. Thunderstorms began developing in the unstable warm sector ahead of a cold front moving east into east Texas and western LA. Very strong low and mid level winds ahead of the cold front brought in ample low level moisture with dewpoints reaching into the 70's near the coast. As temperatures at the surface warmed into the 80s and temps aloft dropped…

Flash Flood · Dec 14, 2022. A strong upper level disturbance and surface low produced several supercell thunderstorms with embedded tornadoes across Southeast Louisiana and Southern Mississippi during the late afternoon and evening hours of Wednesday December 14, 2022. These supercell thunderstorms produced straight line wind damage, flash flooding and tornadoes. ||2 tornadoes have been confirmed in Mississippi from this event. These tornado…

Hurricane (Typhoon) · Aug 29, 2021. The ninth named storm, fourth hurricane, and second major hurricane of the 2021 Atlantic hurricane season, Ida originated from a tropical wave in the Caribbean Sea on August 23rd. On August 26th, the wave developed into a tropical depression, which organized further and became Tropical Storm Ida later that day, near Grand Cayman. On a northwestward track, Ida intensified into a hurricane on August 27, just before…

Tropical Storm · Oct 9, 2020. Delta first developed into a tropical depression in the Caribbean just south of Jamaica on the afternoon of October 4th. As it tracked across the western Caribbean, it rapidly intensified into a Category 4 hurricane. In fact, intensifying from tropical depression to Category strength in 40 hours is the fastest rate of intensification of any storm on record in the Atlantic Basin. Delta quickly weakened to a categor…

The zones you’ll see on the map

Every colour on the map above is a place on this drawing: where the ground sits relative to the flood FEMA plans for.

Cross-section of a river floodplainDiagram: a river valley. The floodway is the channel and the land beside it; the 1%-annual-chance flood surface (the base flood elevation) covers the valley floor as zone A or AE; a narrow band higher up is shaded X, the 0.2% floodplain; higher ground is X.0.2% CHANCE A YEAR (500-YEAR)BASE FLOOD ELEVATION · 1% A YEARXAEFloodwayAEX
  1. A / AE Inside the 1%-a-year floodplain: about a 26% chance of flooding over a 30-year mortgage. AE has a mapped base flood elevation; plain A does not.
  2. Floodway The channel and the land beside it that has to be kept clear enough to carry the flood. Building here is tightly limited.
  3. X shaded The 0.2% (500-year) floodplain, plus some levee-protected and very shallow flood areas.
  4. X Outside both lines. No federal requirement to insure, which is not the same as no risk.

Flood insurance in Amite County

If a building in Amite County is in a high-risk zone (A or V) and its mortgage comes from a federally regulated or insured lender, or is federally backed, flood insurance is required.

Outside those zones it is optional, and often worth having: from 2014 to 2024 nearly one-third of NFIP claims came from outside the high-risk Special Flood Hazard Area. Since Risk Rating 2.0, NFIP premiums are set for each building, so the only reliable price is a quote: FloodSmart.gov or a local agent.
