Bexar and other metro counties under Flash Flood Warning as heavy downpours move through region

TEXAS, USA — San Antonio and most of greater Bexar County is under a Flash Flood Warning until 11:45 p.m. as heavy downpours move through the region Friday night. One to three inches of rain is likely in the evening hours. 

A Flash Flood Warning is also in effect for Comal County until 10:30 p.m.

And another Flash Flood Warning is in place for southeastern Bexar County, northwestern Wilson County and most of Guadalupe County until 12:15 a.m. Saturday.

As of 10 p.m., more than 40 Bexar County roads were closed due to high water danger, mainly on the north and northwest sides. Those closures can be seen below. 

Meanwhile, a Flash Flood Watch is in place for Bexar and other surrounding counties until Saturday evening.

There is also a marginal for severe storms Saturday with the main threats being large hail and isolated tornadoes.

“The risk for severe weather over the weekend is a one our of five risk, meaning the threat will be much lower compared to what we had Wednesday night, but it should still be taken seriously,” according to KENS 5 Meteorologist Andrew Wilson.

Flash flooding is forecast to be the main risk with the storms over the weekend with multiple waves of heavy rain passing through, putting down high amounts of rainfall in short periods of time.

Our first good batch of rain will be Friday night, which is when we can expect a few heavy showers east of I-35.

Another round of off and on showers will move through late Saturday morning.

Shower activity will pick-up throughout the day on Saturday with increased shower and thunderstorm activity into the early afternoon.

This is also when we will have the chance for strong storms.

By 2:30 p.m., a bulk of the heavy showers and storms will move over the Coastal Plains region, which is also where some of the higher rainfall totals are expected.

As we move into Saturday evening, most of the storms will start to move out of the region and drier conditions will move in by Sunday morning.

We can expect a large amount of rain throughout the next seven days with a majority of the rain falling from Friday through Sunday.

Expect totals east of I-35 to be anywhere from 2.5″ to 6″ and those west of I-35 may see anywhere from 1.5″ to 3″ of rain.

Remember to avoid flooded areas and never try to drive through flood waters.

When severe weather threatens the area, it is important to know what risks a storm can bring and what you should do to stay safe. 

One of the most important things to know is where you are located on a map, so when a watch or warning is put into place, you can identify if you are at risk. When the National Weather Service puts out warnings, they are county-based and sometimes include cities as well. It is important to know where you live in the county and that you can identify it on a map.

It is also important to know the difference between a watch and a warning. A watch means that conditions are favorable for something to happen, but a warning means that something has developed and it is important to take action.

So, what would cause a thunderstorm to be qualified as a “severe” thunderstorm?

Hail that is one inch large is also considered to be about the size of a quarter.

Another ingredient that would lead to a storm becoming severe is if winds are 58 mph or greater.

Winds at this strength could cause damage to roofs and could even cause trees to be knocked down.

Finally, if a tornado is present inside a thunderstorm it would qualify the storm as becoming severe.

In this instance, a tornado warning would be issued.

A tornado watch can be issued for an area if strong storms are expected, and if the storms bring the risk for tornadoes, but not all storms include the threat for tornadoes. The ingredients in the atmosphere for a tornado to form are not always there when storms are present.

If the area you are in is ever under a tornado warning, it is important to know where you should go inside your home.

Head to the lowest, interior room of your home. The basement would be best, but if you don’t have one, head to the first floor of the home and get away from exterior walls, or walls that lead to the outside of the home.

It is also important to stay away from glass. The more walls you can put between you and the outside, the better.

While lightning can be frequent in storms and very dangerous, it does not lead to a storm being qualified as severe.

Remember, when thunder roars, go indoors.

Storms can also lead to flooding. Flooding may not cause a storm to be labeled as being severe, but it is the deadliest kind of weather.

South Texas is known to have major flood events every few years, so it is important to use caution and to always stay out of floodwaters. Remember, turn around, don’t drown.

Entering flood water is very dangerous as you can be swept off of your feet and you don’t know what could be in the water that could hurt you.

The best thing you can do to be ready for severe weather is know what you will do in the event it strikes where you live.

Make sure your family has a severe weather action plan.

Have a place everyone goes inside your home and keep supplies there, such as food, medication, batteries, and flashlights.
