Flooding closes over 100 crossings in Austin

Stunning stat: Areas to the south and east of Austin could receive as many as 6 inches of rain during this set of storms, per a forecast discussion posted by the National Weather Service (NWS) Monday.

• More than 4.5 inches fell in parts of greater Austin over a 12-hour period between Sunday night and Monday morning, per the Lower Colorado River Authority.
• Near Eagle Pass, about 140 miles southwest of San Antonio, as much as 12 inches fell Monday morning.

State of play: As of Monday morning, 107 crossings were closed in Austin.

What's happening: "Really deep moisture" in the atmosphere met a weak cold front from the north, leading to the heavy downpours, Cory Van Pelt, a meteorologist with the NWS New Braunfels office, tells Axios.

Zoom in: The NWS sent out multiple flash flood warnings early Monday.

• Sent when life and property are at risk, the texts bypassed do-not-disturb settings across Austin.
• Travis County's Office of Emergency Management also sent out its own warning at about 1:30am "to reinforce the NWS message," David Wiechmann, a spokesperson for Austin Emergency Management, tells Axios.

• Context: Last July, the NWS faced scrutiny over the timing and number of its alerts in the lead-up to the devastating Hill Country floods.

Zoom out: Despite all the recent precipitation, Austin has seen a total this year of 15.51 inches of rain as of Monday morning — trailing the normal year-to-date accumulation of 16.89, per NWS.

What's next: Expect muggy weather and more rain this week.

• Van Pelt says that a drier midweek could give way to more rain at week's end, with a front coming in from the south.
