🌧️ 𝐖𝐞𝐚𝐭𝐡𝐞𝐫 𝐔𝐩𝐝𝐚𝐭𝐞 𝐟𝐨𝐫 𝐊𝐚𝐭𝐲 | 𝐎𝐯𝐞𝐫𝐧𝐢𝐠𝐡𝐭 𝐒𝐭𝐨𝐫𝐦𝐬 𝐏𝐨𝐬𝐬𝐢𝐛𝐥𝐞

After a brief break, rain and storm chances return tonight into Wednesday morning.

The setup is familiar because this has been the pattern lately: storms develop well west of us, move across Texas overnight, and then the big question becomes how strong they are by the time they reach Southeast Texas. Models are in decent agreement that a line or complex of storms may move toward the Katy area after midnight, with the most likely timing around the 1 AM timeframe.

Rainfall totals may vary quite a bit depending on how the storm line holds together and whether heavier cells move over the same locations. Some areas may only see a quick round of rain, while others could see heavier rainfall, ponding, or street flooding develop during the overnight and early morning hours.

Main things to watch tonight into Wednesday morning:

🌧️ Periods of moderate to heavy rain
⚡ Lightning
💨 Gusty winds, mainly below severe limits
🚗 Ponding or street flooding in poor drainage areas
👀 Reduced visibility during heavier rain
⏰ Possible impacts to the early Wednesday commute

The severe weather threat is on the lower end, but a few stronger storms could still produce gusty winds. The main concern remains heavy rain falling quickly, especially overnight and early Wednesday when water on roads is harder to see.

A few reminders:

✅ Check the forecast before going to bed
✅ Check radar before heading out Wednesday morning
✅ Give yourself extra time if rain impacts the commute
✅ Never drive through water over the road
✅ Have more than one way to receive weather alerts

This is another “check before you go” setup. It may be quiet when you go to sleep and raining when you wake up, because apparently the atmosphere enjoys overnight scheduling.

We will continue monitoring the forecast and share updates as needed.

⚠️ 𝐖𝐞𝐚𝐭𝐡𝐞𝐫 𝐔𝐩𝐝𝐚𝐭𝐞 | 𝐅𝐥𝐚𝐬𝐡 𝐅𝐥𝐨𝐨𝐝 𝐖𝐚𝐫𝐧𝐢𝐧𝐠
4:20 PM Saturday, May 23

The National Weather Service has issued a Flash Flood Warning until 6:15 PM for Katy.

Thunderstorms have produced heavy rainfall across the warned area, with 2 to 3 inches of rain already reported in some locations. Additional rainfall is still possible.

Inside the City of Katy, we have generally received around 0.8 to 1.4 inches over the past hour. The heaviest rain is beginning to move out of the area, and rainfall rates should start to relax.

That said, the hazard is not over the moment the heavy rain stops.

Runoff and water on roadways may remain a problem for a while as drainage systems catch up from the heavy rainfall over a short period of time. Ponding, street flooding, and water in low-lying or poor drainage areas may continue even after the rain lightens.

Please use caution if you are traveling:

✅ Slow down on wet roads
✅ Watch for ponding and standing water
✅ Avoid low spots and poor drainage areas
✅ Never drive through water over the road
✅ Give drainage systems time to catch up

🌧️ 𝐖𝐞𝐚𝐭𝐡𝐞𝐫 𝐔𝐩𝐝𝐚𝐭𝐞 | 𝐖𝐚𝐭𝐜𝐡𝐢𝐧𝐠 𝐓𝐡𝐢𝐬 𝐀𝐟𝐭𝐞𝐫𝐧𝐨𝐨𝐧 𝐚𝐧𝐝 𝐄𝐯𝐞𝐧𝐢𝐧𝐠
12:15 PM Saturday, May 23

Good afternoon, Katy.

We had showers and storms move through earlier this morning, but that does not mean we are finished for the day.

The National Weather Service is watching for additional showers and thunderstorms to develop this afternoon and continue into this evening. The highest flood concern for our area is expected to be midday through this evening, with storms possibly hanging around until later tonight.

The concern is not that everyone will see flooding. The concern is that storms may develop quickly and produce heavy rain over a short period of time. If storms slow down, cluster, or move over the same area, street flooding and ponding could develop quickly.

Main concerns this afternoon and evening:

🌧️ Heavy rainfall
⚡ Frequent lightning
💨 Gusty winds
🚗 Street flooding or ponding
👀 Reduced visibility during heavy rain
🌊 Water collecting in poor drainage areas

A few storms could also become strong, with gusty winds or small hail possible. A brief tornado cannot be completely ruled out, but the main concern remains heavy rainfall and flooding.

What this means for your Saturday plans:

✅ Check the radar before heading out
✅ Keep outdoor plans weather-aware
✅ Give yourself extra time if storms develop
✅ Move indoors if you hear thunder
✅ Do not drive through water over the road
✅ Have more than one way to receive weather alerts

The Flood Watch remains in effect through Monday evening. Additional showers and thunderstorms are possible Sunday and Monday, but the highest concern right now is this afternoon and evening.

We will continue monitoring conditions and share updates as needed.

05/22/2026

🌧️ 𝐖𝐞𝐚𝐭𝐡𝐞𝐫 𝐔𝐩𝐝𝐚𝐭𝐞 | 𝐅𝐥𝐨𝐨𝐝 𝐖𝐚𝐭𝐜𝐡 𝐄𝐱𝐩𝐚𝐧𝐝𝐞𝐝
Friday, May 22

The National Weather Service has expanded the Flood Watch for Southeast Texas, and it now includes more of the Katy area through Monday evening.

A Flood Watch means flooding caused by excessive rainfall is possible. It does not mean flooding is happening everywhere right now, but it does mean conditions could become favorable for flooding if heavier storms develop over the same areas.

For Katy, today may only bring isolated showers or storms. Hopefully it stays quiet, but a few storms could still develop this afternoon as the atmosphere heats up. The main focus is shifting to Saturday into Saturday night, when the atmosphere will be more favorable for storms to develop locally or move into the area from the west.

The biggest question is not whether it rains every hour. It will not. The bigger question is where the strongest storms set up, how slowly they move, and whether multiple storms pass over the same area.

Some storms this weekend may produce:

🌧️ Heavy rainfall
⚡ Frequent lightning
💨 Gusty winds
🚗 Street flooding or ponding
🌊 Rising water in low-lying or poor drainage areas

Rainfall totals may vary a lot across the region. Some spots may not see much, while others could receive several inches in a shorter period of time.

This is one of those forecasts where checking once in the morning may not be enough. Conditions can change quickly, especially if storms develop nearby during the afternoon, evening, or overnight hours.

A few reminders:

✅ Keep checking the forecast and radar
✅ Have more than one way to receive alerts
✅ Give yourself extra time if rain develops
✅ Do not drive through water over the road
✅ Move indoors if you hear thunder
✅ Keep weekend and Memorial Day plans weather-aware

We will continue monitoring the forecast and share updates as needed.

🌧️ 𝐖𝐞𝐚𝐭𝐡𝐞𝐫 𝐔𝐩𝐝𝐚𝐭𝐞 𝐟𝐨𝐫 𝐊𝐚𝐭𝐲 | 𝐊𝐞𝐞𝐩 𝐂𝐡𝐞𝐜𝐤𝐢𝐧𝐠 𝐭𝐡𝐞 𝐅𝐨𝐫𝐞𝐜𝐚𝐬𝐭
8:00 AM Thursday, May 21

Rain continues to move through parts of Southeast Texas today, with the heavier activity mainly staying closer to the coast for now. Around Katy, conditions may vary through the day with periods of light rain, breaks, and the chance for additional showers or storms.

This is the kind of pattern where the forecast can change quickly. Don’t rely on the forecast from the night before as the final answer for your plans. Check the latest forecast and radar before heading out, especially if you have outdoor activities, travel, graduations, services, or weekend plans.

It may not rain the entire time, but additional rounds of showers and storms remain possible through the rest of the week and into the weekend. If storms develop over the same area or slow down, heavy rain could create quick ponding or street flooding.

A few reminders:

✅ Check the forecast and radar before outdoor plans or travel
✅ Keep weekend plans flexible
✅ Have more than one way to receive alerts
✅ Use caution on wet roads
✅ Never drive through water over the road
✅ Move indoors if you hear thunder

We’ll continue monitoring the forecast and share updates as needed.

🌧️ 𝐖𝐞𝐚𝐭𝐡𝐞𝐫 𝐔𝐩𝐝𝐚𝐭𝐞 | 𝐅𝐥𝐨𝐨𝐝 𝐖𝐚𝐭𝐜𝐡 𝐟𝐨𝐫 𝐏𝐨𝐫𝐭𝐢𝐨𝐧𝐬 𝐨𝐟 𝐊𝐚𝐭𝐲
1:00 PM Wednesday, May 20, 2026

Good afternoon, Katy.

The National Weather Service has issued a 𝐅𝐥𝐨𝐨𝐝 𝐖𝐚𝐭𝐜𝐡 𝐟𝐫𝐨𝐦 𝐓𝐡𝐮𝐫𝐬𝐝𝐚𝐲 𝐦𝐨𝐫𝐧𝐢𝐧𝐠 𝐭𝐡𝐫𝐨𝐮𝐠𝐡 𝐌𝐨𝐧𝐝𝐚𝐲 𝐦𝐨𝐫𝐧𝐢𝐧𝐠 for portions of south central and southeast Texas.

𝐅𝐨𝐫𝐭 𝐁𝐞𝐧𝐝 𝐂𝐨𝐮𝐧𝐭𝐲 𝐢𝐬 𝐢𝐧𝐜𝐥𝐮𝐝𝐞𝐝 𝐢𝐧 𝐭𝐡𝐞 𝐅𝐥𝐨𝐨𝐝 𝐖𝐚𝐭𝐜𝐡. At this time, Harris County and Waller County are not included, but the watch could be expanded as the rainfall threat evolves into the weekend.

This watch is mainly focused on the anticipated flood threat over the next 24 to 48 hours, especially for areas that received heavier rainfall last night and this morning and may receive additional heavy rainfall Thursday and Friday.

For Katy, we are in a calmer period right now after last night’s storms and this morning’s rain. The next round of showers and thunderstorms may move toward Southeast Texas Thursday morning, with additional rain chances continuing through the rest of the week and into the holiday weekend.

A Flood Watch means flooding caused by excessive rainfall is possible. It does not mean flooding is happening everywhere right now, but it does mean conditions may become more favorable for flooding as additional rounds of rain move through.

Main concerns:

🌧️ Heavy rainfall
🚗 Street flooding or ponding in poor drainage areas
🌊 Rising creeks, streams, and low-lying areas
👀 Reduced visibility during heavier rain
⚡ Lightning with thunderstorms

Rainfall rates may reach 3 to 4+ inches per hour in the heaviest downpours. Those rates can overwhelm drainage quickly, especially in areas that receive repeated storms.

A few reminders:

✅ Monitor later forecasts
✅ Have more than one way to receive alerts
✅ Give yourself extra time if rain impacts travel
✅ Never drive through water over the road
✅ Be ready to act if Flood Warnings are issued
✅ Keep outdoor and holiday weekend plans flexible

We will continue monitoring the forecast and share updates as needed.

🌩️ 𝐖𝐞𝐚𝐭𝐡𝐞𝐫 𝐔𝐩𝐝𝐚𝐭𝐞 𝐟𝐨𝐫 𝐊𝐚𝐭𝐲 | 𝐒𝐩𝐞𝐜𝐢𝐚𝐥 𝐖𝐞𝐚𝐭𝐡𝐞𝐫 𝐒𝐭𝐚𝐭𝐞𝐦𝐞𝐧𝐭 𝟏𝟐:𝟐𝟎 𝐀𝐌 𝐖𝐞𝐝𝐧𝐞𝐬𝐝𝐚𝐲, 𝐌𝐚𝐲 𝟐𝟎, 𝟐𝟎𝟐𝟔

The National Weather Service has issued a Special Weather Statement for strong thunderstorms impacting portions of Southeast Texas, including Katy, Brookshire, Fulshear, Cinco Ranch, northwestern Fort Bend County, southern Waller County, and west central Harris County through 1:15 AM.

At 12:16 AM, radar showed a cluster of strong thunderstorms along a line from near Bellville to near Eagle Lake. The storms are moving east at 25 mph.

Main concerns:

💨 Wind gusts up to 40 mph
🧊 Pea-size hail
🌧️ Torrential rainfall
⚡ Frequent cloud-to-ground lightning
🚗 Localized street flooding or ponding

We will continue monitoring the storms and provide updates as needed.

🌩️ 𝐖𝐞𝐚𝐭𝐡𝐞𝐫 𝐔𝐩𝐝𝐚𝐭𝐞 𝐟𝐨𝐫 𝐊𝐚𝐭𝐲 | 𝐒𝐩𝐞𝐜𝐢𝐚𝐥 𝐖𝐞𝐚𝐭𝐡𝐞𝐫 𝐒𝐭𝐚𝐭𝐞𝐦𝐞𝐧𝐭 𝟏𝟎:𝟐𝟓 𝐏𝐌 𝐓𝐮𝐞𝐬𝐝𝐚𝐲, 𝐌𝐚𝐲 𝟏𝟗, 𝟐𝟎𝟐𝟔

The National Weather Service has issued a Special Weather Statement for strong thunderstorms impacting portions of Southeast Texas, including Fort Bend, southern Waller, and southern Harris Counties through 11:30 PM.

At 10:17 PM, radar showed a line of strong thunderstorms extending from near Bellville to Addicks Park Ten to Channelview and near Anahuac. The line is moving southwest at 30 mph.

Main concern:

💨 Wind gusts up to 40 mph

Gusty winds may knock down small tree limbs and blow around unsecured outdoor items. Brief heavy rain, lightning, and reduced visibility may also occur as storms move through the area.

Please use caution if driving late tonight, secure loose outdoor items if safe to do so, and continue monitoring for additional updates.

05/19/2026

🌧️ 𝐖𝐞𝐚𝐭𝐡𝐞𝐫 𝐔𝐩𝐝𝐚𝐭𝐞 𝐟𝐨𝐫 𝐊𝐚𝐭𝐲 | 𝐒𝐭𝐨𝐫𝐦𝐬 𝐏𝐨𝐬𝐬𝐢𝐛𝐥𝐞 𝐓𝐨𝐧𝐢𝐠𝐡𝐭 (𝟓/𝟏𝟗)

Here is the updated look for Katy.

We are moving into a wet and stormy pattern that may continue through the rest of the week and into the holiday weekend. This does not mean it will rain the entire time. The concern is that several rounds of storms may move through the region, with breaks in between.

The first period we are watching closely is tonight into early Wednesday morning, but this is not the only window of concern. Additional rounds of showers and thunderstorms remain possible through the rest of the week and into the holiday weekend.

A line or broken line of storms may move toward the area later this evening, generally around the 10 PM timeframe, give or take an hour or two. Another round of storms may be possible early Wednesday morning.

Main concerns tonight:

🌧️ Heavy rainfall
⚡ Frequent lightning
💨 Gusty winds
🧊 Small hail possible
🚗 Brief street flooding or ponding

Katy has been upgraded to a Slight Risk Level 2 of 4 for excessive rainfall today. That does not mean everyone will see flooding, but it does mean storms could produce heavy rain quickly. A few spots could see several inches of rain in a short period, especially where stronger storms develop or multiple storms move over the same location.

A few stronger storms could also produce gusty winds and small hail. Even storms that stay below severe limits can still produce dangerous lightning and heavy downpours.

A few reminders for tonight and Wednesday morning:

✅ Have more than one way to receive weather alerts
✅ Use extra caution if driving late tonight or early Wednesday
✅ Never drive through water over the road
✅ Give yourself extra time Wednesday morning if storms impact the area
✅ Keep outdoor plans flexible through the holiday weekend

This is also Texas Flood Awareness Week, which is a timely reminder that flooding can happen quickly, especially at night when water on roads is harder to see.

We will continue monitoring the forecast and share updates as needed.

05/18/2026

🌧️ 𝐖𝐞𝐭 & 𝐒𝐭𝐨𝐫𝐦𝐲 𝐏𝐚𝐭𝐭𝐞𝐫𝐧 𝐄𝐱𝐩𝐞𝐜𝐭𝐞𝐝 𝐓𝐡𝐢𝐬 𝐖𝐞𝐞𝐤

Katy is heading into a wetter weather pattern beginning late Tuesday and continuing through the rest of the week, with rain chances likely sticking around into the holiday weekend.

This does not mean it will rain the entire time, but several rounds of showers and thunderstorms will be possible. Some storms could produce heavy rainfall, frequent lightning, gusty winds, and brief street flooding or ponding in poor drainage areas.

Katy is currently included in a 𝐌𝐚𝐫𝐠𝐢𝐧𝐚𝐥 𝐑𝐢𝐬𝐤 for excessive rainfall through portions of the week. Localized heavy downpours may develop quickly, especially if storms move over the same area more than once.

This also happens to be Texas Flood Awareness Week, which is a good reminder that flooding is the most common natural disaster in Texas. A few inches of fast-falling rain can create dangerous conditions on roads, especially at night when water is harder to see.

A few reminders:

✅ Stay weather aware this week
✅ Have more than one way to receive alerts
✅ Slow down during heavy rain
✅ Never drive through flooded roads
✅ Check on outdoor plans, graduations, and holiday weekend activities
✅ Keep storm drains near your property clear if you can safely do so

The City of Katy Office of Emergency Management will continue to monitor the forecast and share updates as needed.
