From the storm reports

Flash Flood · Oct 4, 2023. A prolonged period of very heavy rainfall along with severe thunderstorms occurred on October 4th-5th across parts of Northeast Texas. Showers and thunderstorms with 1-3 inch per hour rainfall rates trained in the vicinity of a warm front, which was oriented across the Ark-La-Tex and in adjacent portions of Southeast Oklahoma and Northeast Louisiana. Deep convergence of moisture along the boundary resulted as the…

Flash Flood · Apr 29, 2016. After a brief respite from severe thunderstorms during the predawn hours on April 29th, additional strong to severe thunderstorms developed from the late morning hours through much of the afternoon and evening on April 29th, and lingered through the early morning hours on April 30th. These storms developed along and south of a warm front which lifted into Southeast Oklahoma and the northern sections of Southwest A…

Flash Flood · Jun 10, 2010. A deep upper level trough was nearly stationary across south central Texas with thunderstorms developing to the north and east of the trough during the morning hours of June 9th. The storms propagated into northeast Texas during the afternoon of the 9th and encountered a very unstable airmass. These storms become widespread across the region into the afternoon and evening hours of the 9th and produced large hail…

Flash Flood · Oct 22, 2009. Strong thunderstorms and heavy rainfall accompanied a strong cold front which swung through the region on October 22nd. The storm system which aided in the development of severe thunderstorms, was accompanied by the remnant moisture of Hurricane Rick which was a strong hurricane off the western coast of Mexico several days earlier. Isolated tornadoes were reported across portions of northwest Louisiana with the…

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.

  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.

Flood insurance in Morris County

If a building in Morris 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.
