Just received word from Harris County Precinct #4 that Mercer Botanic Gardens and the Mercer Society (TMS) have cancelled Holiday in the Gardens this Saturday. Reason: expected severe weather including flooding and possible tornadoes.
The event had been scheduled for Saturday, Dec. 8 from 11 a.m. to 5 p.m. at 22306 Aldine Westfield Road in Humble, 77338.
Holiday in the Gardens has been cancelled this year due to expected flooding and severe weather.
Storms forecast to hit the area Friday, Dec. 7, into early Saturday morning could dump as much as 8-10 inches of rain. Jeff Lindner, Harris County meteorologist expects the US59 corridor to be the focus of some of the most intense. He predicts flooding along Cypress Creek which borders the Mercer Botanic Gardens.
Stay tuned for details regarding additional events planned in 2019.
TMS, a nonprofit 501(c)(3) organization, partners with Mercer Botanic Gardens to provide support for ongoing flood recovery efforts, programming, as well as improvements and expansions at Mercer Botanic Gardens. For more information about TMS or to make a donation, visit themercersociety.org.
Since 1974, Mercer has grown to more than 300 acres with more than 20 acres of beautifully maintained gardens in addition to an extensive walking trail system, ponds, ongoing educational and recreational programs, and more. For more information, visit www.hcp4.net/mercer.
Once again, Holiday in the Gardens has been cancelled this year due to expected severe weather.

Now would be a good time to make sure nothing is blocking the storm drains on your street. The National Weather Service has issued a Flash Flood Watch for Houston from Friday afternoon through Saturday morning. This means conditions are favorable for flooding to occur. Heavy rain is expected to impact Houston beginning 6 p.m. Friday, December 7, and periods of intense and/or prolonged rainfall may cause flash flooding.
National Weather Service Flash Flood Prediction as of Dec 6 @ 5:40 a.m.
Protective Actions
Be Prepared. Bring pets inside. Delay travel or outdoor activities during periods of heavy rainfall. If travel is unavoidable, reduce your speed to avoid hydroplaning. Make sure storm drains on your street are clear.
If a Flash Flood Warning is issued for your area:
DO NOT travel. Do not drive through flooded areas. If you see water covering the road, do not attempt to cross it. Only a few inches of water can 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.
National Weather Service Houston/Galveston Forecast Office (weather.gov/hgx).
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.
Avoid Traveling during Periods of Heavy Rain: Rain can reduce visibility and prevent you from seeing the road ahead, which could lead to accidents.
Lake Houston Lowered in Anticipation of Storm
Council Member Dave Martin’s office says that the City of Houston has been lowering Lake Houston water levels since late last night.
Property owners should expect a lowering of up to 18 inches. Should additional lowering be necessary, Council Member Martin will work with Houston Public Works to make sure that everything possible is done to secure life and property in the Lake Houston area.
As of 1:30 a.m. Thursday afternoon, the Coastal Water Authority reported the level of Lake Houston at 41.54 ft. That’s about 12 inches below normal. Pre-releasing water from the Lake creates extra capacity for incoming floodwater to reduce the risk of flooding.
Harris County Meteorologist Discusses Local Impacts
Jeff Lindner, the Harris County meteorologist, also issued a special report this morning warning that, “Flash Flooding of streets along with significant rises on area bayous, creeks, and rivers to flood levels is possible.
Says Lindner, “Powerful upper level storm system moving into S CA and NW MX this morning will track generally eastward and into TX over the next 48 hours. Activity will increase today from the coastal bend northward along the I-35 corridor. Some of this activity will likely affect our far western and southwestern counties later this morning into the afternoon hours.”
Friday-Saturday
Lindner warns, “An excessive rainfall event is likely Friday afternoon-Saturday morning, resulting in flooding.”
“Models continue to suggest near record/record moisture levels will be in place by Friday afternoon. Forecast soundings show little instability, but loaded with plentiful moisture form the surface into the upper levels indicating convection will be very effective at heavy rainfall production. Unfortunately it appears the slow moving surface front will be nearing the US 59 corridor around the time that maximum parameters for heavy rainfall focus over SE TX. This includes a very strong 45-55kt low level jet which will transport copious moisture into the frontals slope. Add in a slow moving surface boundary and a nearly “tropical air mass” and you pretty much have everything needed for excessive rainfall rates.”
Widespread Rainfall of 3-6″, 8-10″ in Places
According to Lindner, widespread rainfall amounts of 3-6 inches appear likely over nearly all of the area with isolated totals of 8-10 inches. It is still somewhat uncertain where those higher isolated totals may occur, but areas along and NW of US 59 may have a slightly greater risk than areas S of US 59. Much of the higher totals will tend to focus closely with the surface front and where it slows at times as it crosses the region. In addition to the overall totals, high hourly rainfall rates of 2-3 inches per hour will be possible which will lead to rapid urban flooding of street systems.”
River Forecast
The National Weather Service predicts significant rises in area watersheds. They say most basins can handle 6 hour totals of 3-4 inches, but anything greater than about 4 inches in 6 hours is going to likely be cause for concern. For Harris County, all of the creeks and bayous will likely see significant rises and exceeding of flood stage levels is possible. Greatest concern at the moment is for the watersheds over the northern half of Harris County. Some structure flooding will be possible if watersheds exceed their banks or intense rainfall rates overwhelm street systems.
They made the following predictions at 12:46 p.m., Thursday.
San Jacinto: minor to moderate flooding expected on the West Fork. Minor flooding on the East Fork
Cypress Creek: minor flooding forecast from Katy Hockley to West Fork of the San Jacinto River
Trinity: minor to moderate flooding expected along the entire river below Riverside
Brazos: Minor flooding expected at Hempstead and Bryan and will likely see at least minor at Richmond and Rosharon
Summary
Timing: Friday morning College Station area, mid to late afternoon Houston area through Saturday morning
Amounts: 3-6 inches widespread isolated 8-10 inches. US59 corridor may get the worst.
Watersheds: flooding of creeks, bayous, and rivers probable
Street Flooding: high threat for street flooding
Severe: a few storms late Friday night may become severe near the coast with a tornado threat.
Forecast Rainfall Amounts
Excessive rainfall amounts for Day 2

This morning, Dr. Charles Campbell, shared a spectacularly beautiful and inspiring photograph with me. He took it right here in Kingwood. It symbolizes all the hope and promise of a new day, maybe even a new year. Dr. Campbell jogs every morning at sunrise in East End Park where he took this shot.

Reconstruction to Date
As I lost myself in this photo, I reflected on the progress our dynamic community has made this year.
Most people have rebuilt from Hurricane Harvey or are at least close to completion.
Most businesses have returned.
Kingwood College should completely re-open in January with $60 million of renovations and new construction.
Kingwood High School also received an estimated $60 million makeover and update.
Memorial Hermann opened a new 45,000 square foot Convenient Care Center in the heart of Town Center.
Flood Mitigation Progress
And to help prevent a repeat of Harvey:
The Army Corps of Engineers has started a $67 million dredging project which it hopes to complete by next April.
City, County, StateandFederal leaders have rallied to urge FEMA and the Corps to extend the project past the mouth of the river. Both of these projects should help move water through the river faster.
Harris County voters approved a historic $2.5 billion Flood Bond. It includes money that will help build the gates and dredge the river on an ongoing basis.
The bond package also includes money to help build additional upstream detention. That will hold water upstream in future flood events.
The SJRA adopted a policy of seasonally lowering Lake Conroe during the peak of spring rains and the Hurricane Season. They will hopefully continue this until other mitigation measures are in place. This helps give us an additional buffer against giant storms.
The City of Houston adopted a policy of lowering Lake Houston, also in anticipation of major storms. Again, this gives the lake extra capacity to absorb more runoff before the river is forced out of its banks. This also is a temporary measure until other mitigation measures are completed.
The county is also buying out properties below the Lake Houston dam in anticipation of higher flow rates once additional gates are installed.
Harris County has purchased floodway property and will convert it to new parks. Construction on Edgewater Park will begin next year and create a second boat launch for area residents.
The City passed a new ordinance requiring homes to be built 2 feet above the 500-year flood plain.
The County and the Corps are starting to open up ditches like the one at River Grove that drains the western third of Kingwood.

New Day for the Community That Refused to Quit
Clearly, we have a lot to be thankful for this Christmas. But as I look back, the thing I am most thankful for is that the people of this community chose not to ignore flood issues. We addressed them head on. As a result, our our homes, health and future will be much safer.
When I moved to Texas almost 40 years ago, I fell in love with the can-do attitude of Texans.
Tell a Texan something can’t be done and he’ll show you how.
Tell a Texan it’s hopeless and she’ll tell you to get out of her way.
And among Texans, few embody this spirit more than Houstonians, especially those in the Lake Houston area.
