🌊 AFTER THE STORM · Oct 1, 2026 Texas floods
Texas flooded this week. Was your street in the water?
On Thursday, October 1, 2026, the National Weather Service issued Flash Flood Warnings across Texas — from the Dallas–Fort Worth metro to the Hill Country to east Texas. Some areas saw 3 to 7 inches of rain in a single morning, with "life-threatening" language in the warnings. Rivers are still cresting across the Hill Country and southeast Texas.
If you live in Texas — or you're buying a home anywhere flood-prone — this is the day to know your official FEMA flood zone. Not the guess. The map.
🕗 Evening update — 8:00 PM ET
- San Antonio metro: the Flash Flood Warning (Bexar, Atascosa, Wilson counties) expired at 7:00 PM CDT after 1–4 inches of rain and "life-threatening" flash flooding — numerous low-water crossings closed, Leon and Olmos Creeks rising. Travel was strongly discouraged across the metro this afternoon.
- Devils River (Val Verde County): UPGRADED to major flood stage — forecast to crest near 18.3 feet this evening at Bakers Crossing and Cauthorn Ranch. The NWS warning language: "Massive flooding destroys anything in the flood plain." River warnings now run through Saturday morning.
- Llano River at Llano: now forecast to crest at 12.8 feet late tonight (flood stage is 10.0 ft) — warning runs from late tonight to Friday evening (NWS Austin/San Antonio, 5:28 PM CDT).
- Llano River near Mason: expected to crest at 20.4 feet late this evening (flood stage 18 ft) — comparable to the 21.4-foot crest of August 1978 (NWS San Angelo).

🌙 Late-night update — 10:20 PM ET
- Houston metro (Grimes, Montgomery, Waller counties): Flash Flood Warning until 10:30 PM CDT — 4–6 inches of rain have fallen with another 2–3 inches possible; flash flooding ongoing or expected to begin shortly (NWS Houston/Galveston, 7:37 PM CDT).
- The storm is moving east: the NWS Houston/Galveston Flood Watch now runs through 7:00 PM CDT Friday — flood risk continues overnight and into Friday across southeast Texas.
- River flooding extends into Saturday: fresh Flood Warnings issued this evening by NWS Austin/San Antonio (through Oct 3), NWS San Angelo (through Oct 2, 10:40 AM CDT) and NWS Fort Worth (through Oct 3, 4:30 AM CDT). Some crests are still ahead of us — the mapped zone, not the headline, is what your insurance bill reads.

Questions everyone's asking tonight
What is a Flash Flood Warning?
A Flash Flood Warning is the National Weather Service's most urgent flood alert: flash flooding is ongoing or expected to begin shortly, typically within minutes to hours. It is more severe than a Flood Watch, which means flooding is possible but not yet occurring. If you are in one, the NWS guidance is blunt: "Turn around, don't drown" — most flood deaths happen in vehicles.
Was my street in the Oct 1 surge zone?
Today's warnings covered east Texas (Tyler, Jacksonville), the San Antonio metro, the Hill Country (Val Verde through Kerr counties), DFW — and by late evening the Houston metro (Grimes, Montgomery, Waller counties, Flash Flood Warning through 10:30 PM CDT). But "warned area" is broad — your address's mapped FEMA zone is specific to your street. Check it free and you'll see exactly which zone letter FEMA assigned your property.
Does one flood mean my home is in a FEMA high-risk zone?
No — and the reverse is also true. FEMA flood zones are long-term risk maps, not a record of which streets flooded once. A street outside a mapped high-risk zone can still flood from extreme rainfall, and a street inside one can go decades without water. The zone letter (A, AE, X, …) is what insurers and lenders use to price risk — which is why knowing your official zone matters even if your street "never floods."
Will today's flooding change my flood insurance quote?
Insurers and lenders price off the official FEMA zone map, not the news. One storm doesn't rewrite your zone overnight — but repeated regional flooding is exactly what triggers FEMA map updates, and when a map is redrawn, quotes and lender requirements can change for entire neighborhoods. Check your zone now; that's your baseline before any revision.
What happened in the September Nor'easter?
On September 26–28, 2026, a Nor'easter slammed the Northeast with storm-surge flooding: about four feet of water in the streets of Surf City, New Jersey, coastal flood warnings across all of Long Island and Atlantic New Jersey/Delaware, and states of emergency in eight NJ counties. New York City, coastal Connecticut and southeast Massachusetts flooded too. (weather.com, nypost.com, Sept 26–28, 2026.)
After the storm: what your zone means for your insurance
How does my FEMA flood zone change my home insurance quote?
Under FEMA's Risk Rating 2.0, premiums are priced to your property — distance to water, flood type, foundation, first-floor height — not just your zone. But the zone letter still moves real money: in Texas, homes in high-risk zones (A, AE, V, VE) average $1,021/year vs $671/year in low-to-moderate zones — 52% more (published 2025 NFIP averages), and a lender holding a federally backed mortgage requires flood insurance there. And "the same zone" doesn't mean the same price: real 2025 Houston Zone AE premiums span ~$493 to over $4,000, driven by first-floor height vs base flood elevation — which is why the full $9 FloodLens report shows typical cost ranges for your zone and the exact questions to ask your agent. In minimal-risk zones (X, C), coverage is optional and typically cheaper — though roughly one in three NFIP claims comes from outside high-risk areas (FEMA-cited; published estimates range 25–40%).
Could the October 1 flooding raise my premium?
Not overnight — but it can start the chain. Repeated regional flooding feeds FEMA map revisions: when a map is redrawn, whole neighborhoods can move into a higher-risk zone, which changes quotes and can trigger lender flood-insurance requirements on refinance or renewal. It's already happening in Texas: Austin's 2026 FEMA map update is reclassifying some Zone X parcels near Barton, Onion, and Shoal Creeks to Zone AE. Risk Rating 2.0 also factors claim history. Checking your zone now gives you the baseline — before any revision.
My lender never mentioned flood insurance — should I care?
If your home sits in a high-risk zone and your mortgage is federally backed, your lender is required to make you carry flood insurance — and if a future map update pulls your street into one, the requirement can land at renewal or refinance. Knowing your zone letter now means the letter doesn't arrive as a surprise on a bill.

Insurance update · October 2026
NFIP is being re-priced — 42% still pay below full risk
A September 2026 Neptune Flood analysis of FEMA data: 1.5 million NFIP policyholders still pay below full-risk price — a $2.6 billion/year gap that is phasing out, with annual increases capped at 18% until subsidies end in the late 2030s. If your premium looks cheap today, the renewal math is already written.
And the maps themselves are negotiable: an approved LOMA (Letter of Map Amendment) can remove the federal flood-insurance requirement entirely when FEMA mapped a parcel wrong. The $9 FloodLens report explains the LOMA path and your renewal math for your exact address.
