Heavy rainfall in just a few hours caused flash flooding in several regions of Texas, leaving roads flooded, vehicles immobilized, and rescue operations underway.

The heaviest rains were concentrated in sectors of the center of the state, where accumulations of between 3 and more than 5 inches were reported in short periods, a situation that quickly raised the water level in streets and highways, according to ABC News.

One of the most visible episodes occurred on Interstate 35, in Waco, where flooding occurred that left people trapped and forced rescues. Teams from Texas Game Wardens and local agencies responded to multiple emergency calls involving drivers and occupants stranded by water.

Videos broadcast from the area showed vehicles stopped among accumulations of water and emergency personnel assisting those who could not leave the area.

A witness identified as Rick Smith reported on social media that several people were trapped on the highway and assured that the situation could have had more serious consequences.

Austin, Houston and other cities remain under surveillance

Weather conditions remain a cause for concern due to a stationary border over the south of the country, a pattern that maintains the daily risk of flash flooding for much of the week.

In the Austin metropolitan area, flash flood warnings were issued and road closures were reported due to accumulation of water and debris. Local authorities asked to avoid unnecessary travel in affected areas.

Meanwhile, much of central and southern Texas remains under a flood watch until at least Tuesday night or early Wednesday, depending on the area. Forecasters warned that rainfall rates could reach between 2 and 4 inches per hour.

Houston could face several consecutive days of heavy rain

Among the areas under greatest attention is Houston, where there is a moderate risk of excessive rain and flooding for several consecutive days.

Forecasts point to widespread accumulations of between 4 and 6 inches in parts of southeastern Texas and parts of Louisiana, Mississippi and Alabama towards the end of the week. In some points, higher amounts could be recorded if the storms repeat over the same areas.

Forecasters are also monitoring a low pressure system coming from the Gulf that could bolster the potential for rain in South Texas during the second half of the week.

Authorities continue to recommend avoiding flooded roads and staying alert for new weather alerts.
