HOUSTON (AP) — Floodwaters closed some Texas schools on Monday after days of heavy rains pummeled the Houston area and led to hundreds of rescues including people who were standed on rooftops.

A 5-year-old boy died after riding in a car that was swept away in fast waters, authorities said.

Although forecasters expected storms to begin tapering off in southeastern Texas, high waters continued to close some roads and left residents facing lengthy cleanups in neighborhoods where rising river levels led to weekend evacuation orders.

Houston is one of the most flood-prone metro areas in the country. Hurricane Harvey in 2017 dumped historic rainfall that flooded thousands of homes and resulted in more than 60,000 rescues.

In one soggy area of Houston, school officials in Channelview canceled classes and said a survey of their employees found many of them had experienced circumstances that would prevent them from coming to work.
