10/24/25 @ 5PM– FEMA and the National Weather Service Houston/Galveston office have issued a flood watch for the Houston region that will last until October 26 at 5:00AM CDT. See details below.
WHAT
Flooding caused by excessive rainfall is possible.
WHERE
A portion of southeast Texas, including the following areas, Austin, Bolivar Peninsula, Brazoria Islands, Brazos, Burleson, Chambers, Coastal Brazoria, Coastal Galveston, Coastal Harris, Coastal Matagorda, Colorado, Fort Bend, Galveston Island, Grimes, Houston, Inland Brazoria, Inland Galveston, Inland Harris, Inland Matagorda, Madison, Matagorda Islands, Montgomery, Northern Liberty, Polk, San Jacinto, Southern Liberty, Trinity, Walker, Waller, Washington and Wharton.
WHEN
From late tonight through early Sunday morning.
IMPACTS
Excessive runoff may result in flooding of rivers, creeks, streams, and other low-lying and flood-prone locations. Flooding may occur in poor drainage and urban areas.
ADDITIONAL DETAILS
Although soils are dry ahead of this heavy rainfall event, guidance for high rainfall rates suggests some instances of flash flooding. There will be two rounds of heavy rainfall with the first one being late Friday night into Saturday morning and then again Saturday evening into early Sunday morning.
Expect widespread rainfall totals of 2-4″ with isolated higher amounts up to 4-6″. Rainfall rates in the strongest storms could exceed 2-3″ per hour. That could lead to flash flooding if these rainfall rates occur for a prolonged period of time.
We will see a lull in the activity late Saturday morning into the afternoon. That will allow for drainage. So, the flood threat is primarily driven by the potential for high rainfall rates.
You should monitor forecasts and be alert for possible Flood Warnings. Those living in areas prone to flooding should be prepared to take action should flooding develop.
RadarScope Image
At 4:15 PM, a large complex of thunderstorms moving across the Hill Country could clearly be seen on radar images.
From Radarscope Pro at 4:15 PM on 10/24/25 using multiple radar sensors.
The warning areas within the boxes above currently indicate:
Hail from 1″ to 2.5″ in diameter
Winds up to 60 MPH
Rainfall of 1′ to 2″ per hour
Jeff Lindner, Harris County Meteorologist, says tornadoes are possible.
The first line of thunderstorms should move through the Lake Houston area shortly before sunrise Saturday.
Second Line of Thunderstorms Expected Saturday Afternoon
Lindner added that a second round of storms looks to develop Saturday afternoon across the Brazos Valley. It should push southeast across our area. This threat will last from mid to late afternoon well into the evening hours on Saturday. The activity will move from northeast to southeast across the area.
ABC13’s future track predicted the Lake Houston area accumulations could approach six inches of rain after the second round clears the area.
The break between rounds of storms should reduce stream and channel flooding.
Lake Report
Lake Conroe is already down a foot and not releasing water.
Lake Houston is down almost half a foot and releasing water at the rate of 4,500 cubic feet per second. The City hopes to lower the lake by a foot ahead of the storm.
Stay Weather Aware
Keep an eye on the sky. Monitor weather forecasts and lake reports. Here’s how.

10/23/25 – Houston District E City Council Member Fred Flickinger announced this afternoon that the City will lower the level of Lake Houston one foot beginning tomorrow morning. The reason: a severe storm arriving Friday night into Saturday morning could dump 2-4 inches of rain over widespread parts of the Lake Houston Watershed. Isolated higher totals up to 6″ are possible where training of thunderstorm cells occurs.
Training refers to a line of thunderstorms that follows a similar path, so that one after another dumps rain on the same neighborhoods.
NOAA’s Severe Storm Center has issued alerts for possible street flooding this weekend for areas that receive high amounts of rain in short periods.
The San Jacinto River Authority is also monitoring rainfall forecasts for the weekend, but has not yet announced whether it will lower Lake Conroe. That lake is already a foot low due to evaporation during the drought. So it likely has enough capacity to absorb the coming rainfall.
Current Lake Level Report as of 5:30 PM 10/23/25
Lake Houston:
Lake Houston is currently at 42.12 feet (normal pool is 42.4 feet). Its gates will be opened beginning tomorrow morning to lower the lake one foot below normal pool, according to pre-release protocols.
Property owners along the lake should secure their shoreline property. Lake Houston levels can be monitored here.
As of 5:30 PM 10/23/25
Lake Conroe:
Lake Conroe is currently at 199.98 feet (normal pool is 201 feet). Lake Conroe levels can be monitored here.
Monitor Official Sources for Current Information:
Periods of moderate to heavy rainfall may continue through late Saturday night or early Sunday morning.
Please use verified news sources for inclement weather information. These include:
Flash flooding is possible. So, stay weather aware and avoid roadways if possible during rain events.
It only takes 6 inches of water to move a car.

Threat Starts Friday, But Expect Heaviest Weather on Saturday
As atmospheric lift increases into Friday night and Saturday, showers and thunderstorms will become more numerous. Jeff Lindner, Harris County’s Meteorologist, says that the potential exists for a complex of storms to form over West Texas Friday evening and move toward the Houston area by sunrise Saturday.
This would likely be the first round of more sustained heavy rainfall, according to Lindner. More rain will linger back to the west, so additional thunderstorms and rainfall could develop into Saturday evening.
A few of the thunderstorms on Saturday could become strong to severe with damaging winds and hail being the main threats. However, they do not appear to threaten widespread areas at the moment. Lindner says wind and hail are secondary to the heavy rainfall threat at the moment.
NOAA’s Storm Prediction Center has placed nearly all of the area under a “marginal” or level 1 out of 5 severe threat for Saturday.
PivotalWeather.com predicts accumulated rainfall in Harris and Montgomery Counties to reach approximately 3.5 inches with higher accumulations to our north and east. But this could change as the storm gets nearer.
Drought May Offset Potential Stream Flooding
Given recent dry conditions, much of this rainfall can be handled. In fact, it is much needed…as long as it does not fall all at once.
NOAA’s Weather Prediction Center has placed the area under a “slight” risk or level 2 out of 4 for flash flooding on Saturday.
Lindner feels that at this time, bayous and creeks should be capable of handling even the higher predicted rainfall totals. He expects to see significant rises on area streams, but feels significant flooding is unlikely at this time.
Lindner also feels that strong southerly winds will push high tides along the coast 4-5 feet higher than normal. Building seas and higher-than-normal tides could create minor coastal flooding at high tides.

10/22/25 – Climate Central, an independent group of scientists and communicators who research weather trends, reported today that 14 separate billion-dollar weather disasters have occurred across the U.S. during the first six months of 2025. They caused $101.4 billion in damages.
Climate Central Now Updating Former NOAA Database
Climate Central has taken over the database of billion-dollar disasters that NOAA stopped updating earlier this year. The self-described “policy neutral” non-profit group addresses climate, sea-level rise, extreme weather, energy, and related topics.
Most Expensive 6 Months on Record
The 14 events recorded just in the first half of this year, between January and June, are well above the inflation-adjusted annual average of 9 events over the past 46 years.
According to Climate Central, the first half of 2025 was the most expensive on record, driven by unprecedented damage from the LA wildfires and damaging Spring severe weather.
The January LA wildfires were the costliest event so far this year — and the costliestwildfire on record — with damages exceeding $60 billion, nearly doubling the previous record.
Need for Data If Costs Shift to States
Climate Central is committed to keeping this critical dataset accessible, timely, and transparent, and will continue to update the analysis to monitor the risk of weather and climate-related disasters.
Adam Smith, Climate Central’s Senior Climate Impacts Scientist, said, “I’m proud to continue this work with Climate Central and to ensure that this vital information remains accessible to the public, researchers, and decision-makers.” Smith formerly headed up NOAA’s U.S. Billion-Dollar Weather and Climate Disasters Program for 15 years.
While the first half of the year set records, it’s unclear how an unusually quiet Atlantic hurricane season while affect the final totals for the year. So far, not one Atlantic hurricane has made landfall in the mainland US this year, a first since 2005.
According to the New York Times, the annual average of billion-dollar disasters has surged from three per year during the 1980s to 19 per year during the last 10 years.
The increase in costs during that same period is not just a function of weather extremes. “As more people and businesses move into areas that are prone to floods and wildfire, more property is vulnerable to damage,” said the Times article.
The Times quoted Andrew Rumbach, a senior fellow at the Urban Institute. He studies climate effects on communities and said the database serves as a powerful signal that decision making is costing us a lot of money.
