Localized flash flooding is possible Monday into Monday night as a cold front will push through the Rio Grande Valley, the National Weather Service in Brownsville/Rio Grande Valley reports.
The NWS said there is the chance for strong to severe storms capable of producing damaging wind and hail along with localized flash flooding.
Although the risk is marginal, weather forecasters urge residents to monitor the weather.
Total rainfall of 2 to 3 inches over a couple of hours in poor drainage areas of the Valley will result in 1 to 2 feet of water depth and nuisance flooding, the NWS reports.
Because there is a marginal risk for severe weather, damaging winds and hail are the primary concerns.
There is moderate uncertainty as to where the heaviest rain will set up, with the Lower and Middle Rio Grande Valley favored for the heaviest rain at this time, according to the NWS.
“While there is some uncertainty with regards to severe weather potential and flash flooding potential, there is high confidence in a “feels like” temperature drop of 20 to 30 degrees from Monday afternoon to Tuesday. Minor coastal flooding, high surf, and dangerous rip currents will also be possible following the cold front,” meteorologist said.
The severe weather threat is expected between noon Monday through 7 a.m. Tuesday. The flash flooding threat is also expected through the same time, but could be extended into Tuesday afternoon, according to the NWS.
Strong to severe storms may include gusty winds up to 60 mph, with pea to nickel sized hail possible.
The NWS report there is still time to prepare for the severe weather and urge motorists to and residents to do the following:
>> Check tire tread wear and pressure and repair/replace.
>> Check brake pads/shoes for wear and replace if needed
>> Check windshield wipers for dry rot and replace immediately to give a clear view
>> Remove debris from drainage ditches, cleanouts, and canals to be on the safe side
>> Check roofs, siding, etc. for loose items and fasten down.
>> Protect/tie down/move outdoor ornamentals, inflatables, holiday decorations, etc.
>> Have a plan to protect life and property (vehicles) before any hail falls. For vehicles, plant to move them to a garage or carport ahead of time.
