County emergency office
Dallas County is inland, off the hurricane evacuation zone map for its state, which covers the coast. Rain from a hurricane still floods inland places. Your county emergency office announces evacuations, shelters and alert sign-ups.
Recent burn areas
3 fires that started in Dallas County since January 1, 2021 have a mapped perimeter, covering 216 acres in all.
Largest
| Fire | Year | Acres |
|---|---|---|
| Keswick | 2022 | 192 |
| Cedar Hill | 2023 | 12 |
| Combine West | 2022 | 11 |
Acres are each fire’s whole mapped area, which can reach past the county line.
Burned ground soaks up less rain, so water can run off faster than usual in a heavy storm. Watch for flood warnings when heavy rain is forecast.

Landslide-prone ground
USGS maps about 21% of Dallas County as ground susceptible to landslides. Its national inventory lists 2 documented landslides in the county.
This is a county-wide figure, not a rating for your spot. Steep slopes, road cuts and burned hillsides above you matter most in heavy rain.
From the USGS U.S. Landslide Inventory and Susceptibility data release (2024). Susceptible ground is terrain steep and high enough for landslides like those mapped in similar places. The inventory counts only slides someone mapped, and some states map few, so a low count doesn’t mean the ground is stable.
