Cold Front Coming: What Corpus Christi Yards Need This Week

A cold front is expected to reach Corpus Christi late Friday into early Saturday, Oct. 16 to 17, according to the National Weather Service Corpus Christi forecast discussion issued early Monday, Oct. 12. Until then the Coastal Bend stays warm and humid, with highs near 93 and minor coastal flooding along the shore. For homeowners, this is a good week to tidy the yard before the wind shifts, keep watering to the Stage 1 schedule, and watch St. Augustine lawns for the first signs of fall patch disease.

What the forecast says for Corpus Christi this week

The Monday morning discussion from NWS Corpus Christi lays out three things worth knowing:

• Coastal flooding: a Coastal Flood Advisory runs until 1 a.m. Tuesday for coastal counties, and forecasters say minor coastal flooding could continue into the middle of the week.
• Warm, humid days through Thursday: the forecast high for Corpus Christi is 93 on Monday and Tuesday. Rain chances stay low, mostly brief sea-breeze showers.
• A cold front late Friday into early Saturday: the main forecast models now agree a front will come through, but how strong it will be is still uncertain and forecaster confidence is low. Behind it, winds turn to the north and northeast and get stronger, with cooler temperatures for the weekend.

The National Hurricane Center’s Monday outlook shows no system in the Gulf. The only area it is watching is far out in the eastern Atlantic near the Cabo Verde Islands. Forecasts change, so check the NWS page again Thursday before you finish weekend plans.

How to prep your yard before a cold front in Corpus Christi

A fall front here usually brings a few hours of gusty north wind, not a freeze, but the wind shift alone will move anything left loose. Before Friday afternoon:

• Put away or tie down patio cushions, umbrellas, trash cans, kids’ toys and lightweight furniture. Anchor grills and keep propane tanks upright and secured.
• Look up at trees along the driveway and roofline. Hanging or cracked limbs that held through the summer can drop when the wind swings around from the north. Oaks can be trimmed this time of year; leave anything near a power line to the utility.
• Rake or blow grass clippings and leaves back onto the lawn or into bags, not into the street. Corpus Christi storm drains carry water straight to the bays.
• If you live in a low spot near the bay or Oso Creek, move tools, bagged mulch and anything you don’t want soaked off the ground while the coastal flood advisory is in effect.

If the list is longer than one Saturday morning, our seasonal cleanup and storm prep service handles loose debris, limb pickup and bed cleanup in one visit.

Is Corpus Christi still under Stage 1 water restrictions?

Yes. The City of Corpus Christi reports combined storage in Lake Corpus Christi and Choke Canyon at 39.0 percent as of Oct. 8, on its Corpus Christi Water page. Stage 1 began when combined storage dropped below 40 percent, and under the city’s drought plan it can end only when storage rises above 50 percent. A few showers this week will not change that.

Under Stage 1, lawns can be watered once a week on your assigned day, before 10 a.m. or after 6 p.m. Pick the morning window. Watering in the evening leaves grass wet overnight, which is exactly what fall lawn diseases need. Cooler weather after the front also means your lawn uses less water, so a deep soak once a week is enough.

Watch St. Augustine for large patch as nights cool

Large patch is a fungal disease that shows up in St. Augustine and zoysia lawns in fall and spring, starting as circular brown or yellow areas that can spread several feet across. Texas A&M AgriLife Extension says preventive fungicide works best when soil temperatures drop below 70 degrees in the fall, before symptoms appear, and that fungicide does little once the disease is visible. Damaged grass will not recover until the following spring.

AgriLife’s prevention list is simple: water early in the morning, reduce how long the grass stays wet, improve drainage, keep nitrogen balanced and mow at the proper height. For St. Augustine that means 2.5 to 3.5 inches, never scalped. In Corpus Christi, the last nitrogen application of the year should go down by Nov. 1, and fall feedings should stay light. A weekly lawn maintenance visit keeps mowing height steady and gives someone a regular look at the turf so patches get caught early.

City brush pickup this month

The city’s heavy brush and bulky item schedule has Section 9-C collecting Oct. 14 to 18 and 9-D Oct. 21 to 25. Piles must be no bigger than 6 by 10 by 6 feet, limited to one truckload, kept out of the street, gutter and ditch, and brush must be piled separately from bulky items. If your section already passed, or you have more than one load, a private haul-off is the other option. Our winter yard prep guide covers what else to finish before December.

Frequently asked questions

Will the cold front bring a freeze to Corpus Christi?
Nothing in the current NWS discussion points to freezing temperatures. The front is expected to bring cooler air and stronger north winds, but forecasters say its strength is still uncertain. Check the NWS Corpus Christi forecast later in the week.

Should I fertilize my lawn before the cold front?
Only lightly, if at all. AgriLife guidance for Corpus Christi is to finish nitrogen by Nov. 1 and keep fall rates low, because heavy fall nitrogen feeds large patch. Water on your Stage 1 day in the morning instead.
