🚨 𝐅𝐥𝐨𝐨𝐝 𝐖𝐚𝐭𝐜𝐡 𝐔𝐩𝐝𝐚𝐭𝐞 – 𝐍𝐨𝐰 𝐈𝐧𝐜𝐥𝐮𝐝𝐞𝐬 𝐇𝐚𝐫𝐫𝐢𝐬, 𝐅𝐨𝐫𝐭 𝐁𝐞𝐧𝐝 & 𝐖𝐚𝐥𝐥𝐞𝐫 𝐂𝐨𝐮𝐧𝐭𝐢𝐞𝐬 🚨

The Flood Watch has been expanded and now includes Harris, Fort Bend, and Waller Counties. It remains in effect through 7:00 PM on Thursday, June 12th.

💧 What to Know:
Heavy rainfall could lead to flooding in low-lying areas, creeks, streams, and urban spots with poor drainage. The latest model runs are now showing deeper moisture and storm activity shifting closer to the Houston metro area, increasing the flood threat locally.

🌧️ When:
Storms are expected to move in late tonight into Thursday morning, with the heaviest rainfall possible between 3:00–9:00 AM. Some storms could repeatedly impact the same areas, increasing the chance for flash flooding. Wind gusts up to 40 mph are also possible with the main line of storms.

⚠️ Potential Impacts:

Flash flooding in flood-prone areas

Creeks and streams may overflow

Travel disruptions possible

📢 Stay Alert:
Monitor weather forecasts and be ready to act if a Flood Warning is issued.

We’re in an active storm pattern, and it’s one of those days where we need to keep an eye on the radar.

👉 This Morning into Early Afternoon:
A cluster of storms from the west is slowly drifting into our area. We expect heavy rain to arrive by around 10 AM, then gradually taper into lighter rain through the early afternoon. Rainfall totals could reach 1 to 2 inches in some spots.

👉 This Evening:
We’re watching for another round of storms to redevelop to our west and possibly move into our area tonight. These could bring gusty winds, hail, and more heavy rain.

🚨 What’s the Risk Today?

• Slight Risk (Level 2 of 4) for flooding – especially on streets with poor drainage or areas that have already seen rain this week.

• Slight Risk (Level 2 of 5) for severe storms

• Damaging winds 🌬️

• Hail up to 1 inch ⛈️

• A brief tornado can’t be ruled out 🌪️

🟡 While a Flood Watch is in effect north of Katy, we could still see street flooding here, especially if we get hit by a stronger storm.

📲 Stay weather-aware, make sure you can receive alerts.

We’ll keep you updated if anything changes.

🌩️𝐌𝐨𝐧𝐝𝐚𝐲 𝐀𝐟𝐭𝐞𝐫𝐧𝐨𝐨𝐧 𝐒𝐭𝐨𝐫𝐦𝐬 𝐏𝐨𝐬𝐬𝐢𝐛𝐥𝐞

There’s a chance for strong to severe storms this afternoon and evening mainly between 4 PM and 9 PM.

🔸 Storms that do develop could bring:

☑️ Large hail in the strongest cells
☑️ Damaging wind gusts
☑️ Locally heavy rainfall that could lead to quick ponding on streets or in low-lying areas

Storms are expected to form north of our area and could drift south into Katy later today. If they hold together, we may see impacts during the evening commute.

This is just the start of an active weather pattern, with more rounds of rain and storms possible through midweek. We’ll keep sharing updates as the forecast becomes clearer.

⛈️ Severe Thunderstorm Watch in Effect for Katy Until 7:00 AM – Monday, June 9

A line of storms is moving in from North Texas and may reach the Katy area early Monday morning.

🌬️ If we are impacted by severe storms, the potential hazards include:

Strong wind gusts

Hail

Brief heavy rainfall, possibly during the morning commute

Some of these storms could strengthen as they move closer to the region.

⚠️ A Severe Thunderstorm Watch means conditions are favorable for storms that could become severe. Please stay weather-aware during the early morning hours, especially if you’re heading out for work or school.

06/04/2025

Heads up if you're out and about this afternoon—The National Weather Service has issued a Flood Advisory for parts of Fort Bend, Harris, and Waller Counties, including Katy.

💧 Rain gauges in areas east and southeast of Katy were picking up 2–3 inches per hour, mainly near Highway 6 and beyond. While the storms are moving, localized flooding in poor drainage spots is possible.

📍 For Katy – we’re included in the advisory, but the heaviest rain fell east of town. Still, if you're traveling that way, take it slow and watch for ponding on the roads.

🌦️ 𝐖𝐞𝐝𝐧𝐞𝐬𝐝𝐚𝐲 𝐖𝐞𝐚𝐭𝐡𝐞𝐫 𝐁𝐫𝐢𝐞𝐟𝐢𝐧𝐠 – 𝐒𝐜𝐚𝐭𝐭𝐞𝐫𝐞𝐝 𝐒𝐭𝐨𝐫𝐦𝐬 𝐏𝐨𝐬𝐬𝐢𝐛𝐥𝐞 𝐓𝐨𝐝𝐚𝐲

🔍 Key Points:

•🌩️ There's a Marginal Risk (Level 1 of 5) for isolated strong to severe storms today.

•💨 The strongest storms could produce isolated strong wind gusts.

•🌧️ Expect scattered activity—some areas will stay dry, others could see brief downpours and lightning.

•⚡ Activity will wind down after sunset.

👀 What’s Driving This?
A weak front is stalling out just north of the area today, but it’s close enough to stir up the atmosphere and make things a bit more interesting. Combine that with the afternoon seabreeze and a warm, unstable air mass, and we’ve got just enough ingredients for scattered showers and storms to develop. While not widespread, a stronger storm or two could still pack a punch with gusty winds and heavy rain.

🌩️ 𝐖𝐞𝐚𝐭𝐡𝐞𝐫 𝐔𝐩𝐝𝐚𝐭𝐞 𝐟𝐨𝐫 𝐊𝐚𝐭𝐲 – 𝐒𝐮𝐧𝐝𝐚𝐲, 𝐉𝐮𝐧𝐞 𝟏 🌩️

We’re tracking isolated to scattered strong to severe thunderstorms that could impact the Katy area as early as 2 PM and continuing through midnight. Storms are expected to develop first in the Brazos Valley and Piney Woods areas, then move southward into the Katy area later this afternoon and evening.

Here’s what you need to know:

✅ 𝐌𝐚𝐢𝐧 𝐭𝐡𝐫𝐞𝐚𝐭𝐬:
Large hail (some storms could produce hail up to 2" in diameter, especially in areas north of Katy)

Damaging wind gusts (potential for winds above 57 mph)

Heavy downpours that could cause brief ponding on roadways and low-lying spots

A brief tornado cannot be completely ruled out, though the overall risk is low

💧 𝐑𝐚𝐢𝐧𝐟𝐚𝐥𝐥:
Most of us won’t see a lot of rain, but any strong storm that develops could quickly drop 1.5 to 2+ inches of rain in a short time.

Localized street flooding is possible in areas with poor drainage.

Stay weather-aware today and tonight, and keep an eye on updates in case warnings are issued.

🌦️ 𝐖𝐡𝐚𝐭’𝐬 𝐚𝐡𝐞𝐚𝐝:
There is still some uncertainty because guidance does not agree on how things will evolve. Some forecasts show morning storms weakening before redevelopment this afternoon, while others suggest ongoing activity from north Texas tracking southward. Either scenario, or a mix of both, is possible. Scattered strong storms could also pop up instead of a well-organized cluster. We are monitoring closely and will share updates if warnings are issued.

🚨 𝐖𝐞𝐝𝐧𝐞𝐬𝐝𝐚𝐲 𝐖𝐞𝐚𝐭𝐡𝐞𝐫 𝐔𝐩𝐝𝐚𝐭𝐞 🚨

A cluster of storms to the southeast of Katy is moving this way this morning, bringing wind gusts up to 40 mph and pea-sized hail. These storms will continue to move through the region over the next few hours. Please use caution if you’re out on the roads this morning.

🌦️ Here’s what to expect today and tomorrow: 🌦️

Today (Wednesday):

• Morning: Storms moving in from the southeast with gusty winds and small hail.

• Afternoon: A larger cluster of storms moving in from the west, with damaging winds (gusts over 58 mph), large hail (1”+), and heavy rainfall that could lead to ponding on roads and minor flooding in low-lying areas.

• Evening/Night: Another round of storms could develop late tonight, especially north and east of Katy, but they’re expected to be weaker.

Thursday:

• Another active weather day with isolated showers and storms in the morning.

• In the afternoon, storms may become more widespread and stronger, bringing another chance of damaging winds, hail, and heavy downpours.

📊 Risk Levels for Katy 📊

• The Storm Prediction Center (SPC) has placed all of Southeast Texas, including Katy, under a Marginal Risk (Level 1 of 5) for severe storms today and tomorrow. This means there’s a small chance (5–14%) of severe winds and 1” hail within 25 miles of any point.

• The Weather Prediction Center (WPC) has placed our area in a Slight Risk (Level 2 of 4) for excessive rainfall today, meaning there’s a better chance for heavy downpours and localized flooding. Tomorrow, we’re under a Marginal Risk (Level 1 of 4) for excessive rainfall.

🌧️ Stay Weather-Ready! 🌧️

• Monitor the radar and be alert for rapidly changing conditions.
