Flash flood risk looms over Houston's Memorial Day weekend

Threat level: The latest National Weather Service forecast indicates the flood risk is highest on Saturday for Houston and much of Southeast Texas but lasts through at least Monday.

• Repeated rounds of rainfall at the same location could inundate drainage systems and lead to street flooding, forecasters say. Some rivers and bayous could also experience minor flooding.

Driving the news: The ground is saturated from the rain we've had so far this week, making it difficult to absorb any additional rainfall, NWS Houston meteorologist Andy McNeel tells Axios.

What they're saying: "That raises a little bit of a natural risk for some potential flash flooding in flood-prone areas," McNeel says, adding much of the area could see 4 to 6 inches of rain by Monday.

• "We'll just need to keep an eye on ... where those locally heavier bands take shape," he says.

Between the lines: Space City Weather's flood threat indicator is at Stage 2 of 5 this weekend indicating some streets and highways might briefly flood.

Zoom out: Despite this weekend's heavy rain forecast, Houston and much of Texas are forecast to see below-average rainfall this summer.

The bottom line: Forecasters advise monitoring weather conditions and having multiple ways to receive weather alerts.
