4/30/2024 3:30 p.m. Weather Information
The City of Houston continues to monitor the level of bayous and lakes in the area following the recent severe weather to our north.
Houstonians are encouraged to sign up for emergency alerts at AlertHouston.org. This is the official emergency notification system for the City of Houston where important information will be shared.
Lake Houston: Lake Houston is currently at 43.30 feet (normal pool is 42.4 feet) All gates on the spillway dam are open and discharging water over the spillway. Gates on Lake Houston will remain open until Lake Houston returns to normal pool. Property owners along the lake should secure property along the shoreline. Water levels throughout the lake are elevated and will continue to rise to the tops of bulkheads and docks at several locations but it will begin to level off over the weekend before receding into next week. Lake Houston levels can be monitored here.
Lake Conroe: Lake Conroe is currently at 202.61 feet (normal pool is 201 feet) Lake Conroe levels can be monitored here.
East Fork of the San Jacinto River:
The river is going to rise 10-15 ft from current levels tonight at FM 1485 and FM 2090…widespread and significant inundation will be in place by Wednesday morning.
Major flooding is in progress or will occur late today into tonight and Wednesday along the East Fork of the San Jacinto River in southeast Montgomery and northeast Harris Counties.
Significant rises today at Cleveland will be rapidly translating downstream this afternoon and tonight into the Plum Grove area of SE Montgomery County and the FM 1485 area of NE Harris County.
Widespread low-land flooding will occur along the river with numerous streets impacted in Harris County:
- FM 1485 will be under several feet of water and impassable
- Flows may approach the deck or approaches of the HWY 99 bridge over the river
River Terrace:
Flooding of the following streets is likely. Elevated homes will be cut off
- River Terrace
- Elm
- Pine
- Cherry Laurel
- Holly
- Cypress
Cypress Point:
The following streets will be flooded (closest to the river). Elevated homes will be cut off:
- Blue Lake
- Oak Knoll
- Wild Oak
- Birchwood
Commons of Lake Houston/Lakewood Heights:
These neighborhoods with homes close to the waterfront could see lake levels rise up to the bulkheads and even into the yards. Some roads may become impassable. We do not expect any structures to flood in these areas.
Flooding will occur in the low-lying undeveloped areas of Kingwood that back up to the East Fork of the San Jacinto River. This is mostly land near the river or backyards with bulkheads that front the river. Structure flooding is NOT expected in Kingwood.
West Fork of the San Jacinto River:
Much of the rainfall fell above (north) of Lake Conroe and Lake Conroe will be able to buffer some of this inflow. Lake Conroe pool elevation appears to have peaked early this morning. Additionally, heavy rainfall largely missed Spring and Cypress Creeks and only modest amounts occurred along middle and upper Lake Creek so additional inflows below Lake Conroe look to be minimal. The river is not expected to reach flood stage at US 59, but will continue to monitor for any changes.
Monitor Official Sources for Current Information:
Please remember it is important to utilize verified news sources for inclement weather information as well as tune in to local news stations for changing forecasts. Harris County Flood Warning System (harriscountyfws.org), Houston TranStar (houstontranstar.org), and the National Weather Service Houston/Galveston Forecast Office (weather.gov/hgx).
To monitor current water levels at Lake Houston, visit www.coastalwaterauthority.org. To see current levels for Lake Conroe you can visit www.sjra.net. Please also keep in mind with rain events flash flooding is always possible, stay weather aware and avoid roadways if possible during rain events. It only take 6 inches of water to move a car. Always turn around, don't drown.
Monitor Stream, Bayou, and Creek Conditions: Rain may move repeatedly across the same area, causing creeks and bayous to rise and possibly exceed their banks. Stay informed of current conditions and avoid traveling near creeks and bayous. You can monitor streams and rivers here at the River Forecast Center.
Protective Actions
People in the area should avoid the waterways as they rise. Residents near the waterways should make preparations in the event they are not able to leave their homes due to high water.
Turn Around, Don't Drown®: Do not drive through flooded areas. If you see water covering the road, do not attempt to cross it. Only takes a few inches of water to float a vehicle . If you find yourself in a dangerous situation where your vehicle is taking on water, get out of the vehicle, get to a higher position, and call 911.
