Starting today, those in San Antonio should prepare for more than just light rain and might want to grab an umbrella.

Currently, a flood watch is in effect for all of San Antonio, including Bexar County, until Thursday at 7 PM, and the ground is already saturated from previous rainfall. Weather authorities warn that even if the amount of rain is not significant, the risk of flooding may continue.

This rain is different from a simple passing shower. Since last weekend, there has been a lot of rain, saturating the ground, and tropical moisture combined with upper-level low pressure continues to linger over South Central Texas, causing repeated formation of rain clouds.

Today, there may be some areas where the intensity weakens, but there is still a possibility of heavy rain from Tuesday evening through Thursday.

The areas under this flood watch include not only Bexar County, where San Antonio is located, but also Comal, Hays, Kendall, Medina, Travis, Williamson, and over 20 counties in South Central Texas. Some areas are expected to receive total rainfall of 2 to 6 inches (about 50 to 150 mm), with localized amounts potentially reaching 10 to 15 inches (about 250 to 380 mm).

In San Antonio, particular attention should be paid to areas around Leon Creek, Salado Creek, and the San Antonio River. These areas may appear to be small streams under normal conditions, but during heavy rain, the water levels can rise very quickly.

Drivers should not take low-water crossings lightly.

In Texas, every year, there are incidents where vehicles are submerged or abandoned after attempting to cross flooded roads, ultimately being swept away by the current.

Even if it looks shallow, if it seems dangerous, the safety rule "Turn Around, Don't Drown" is emphasized for a reason.

At home, check to ensure that drains and gutters are not blocked by leaves or debris, and if you have experienced flooding in the past, it is advisable to move electronics and valuables to higher ground. Preparing flashlights, extra batteries, and a first aid kit can help you be ready for sudden power outages. If you have pets, it is safest to keep them indoors during the rain.

Your commute may also be affected. Some roads may be temporarily closed, and if flooding occurs, detoured traffic may lead to longer travel times.

Fortunately, it is expected that weather conditions will gradually improve over time, but as rain intensifies again, river and creek levels can rise quickly, so it is important to continuously check real-time weather information and guidance from local authorities.

San Antonio typically has relatively dry weather, but once tropical moisture moves in, significant rainfall can occur in a short time.

This time, being a bit more cautious rather than thinking "it will be fine" is the best preparation.

By avoiding flooded roads, planning outings with flexibility, and regularly checking weather conditions, you can navigate this heavy rainfall more safely.
