Washington DC received its highest single-day rainfall total of the year Sunday, and more heavy rain is on its way to send the area into another flood watch.
Rain began falling again early Wednesday morning in DC, which already had received 1.75 inches of rain to begin the month, according to National Weather Service data.
The NWS issued a preemptive flood watch at 4:30 p.m. Tuesday, writing that "heavy rainfall may produce instances of flash flooding" Wednesday morning.
Here's what to know about the flood watch and the week of rain in the District.
Washington DC weather: Wednesday's forecast and what's upcoming
Wednesday's flood watch is in effect until 11 a.m. as ongoing showers and isolated thunderstorms continue through the morning.
Some areas may see 2 to 4 inches of rain within several hours, the National
Weather Service says.
"Excessive runoff may result in flooding of rivers, creeks, streams, and other low-lying and flood-prone locations," according to the advisory. "Flooding may occur in poor drainage and urban areas. Low-water crossings may be flooded."
But with more rain in the forecast, it's possible DC could receive another flood watch or see its current one extended.
More thunderstorms are in the forecast later in the day Wednesday, with Capital Weather expecting scattered showers and storms Thursday afternoon and night. As the week continues, "late-day isolated to scattered showers and storms are possible each day" during the weekend, possibly lingering into next week.
How much does it rain in August in Washington DC?
On average, DC gets 3.54 inches of rain in August, meaning the city is already nearing half of its monthly rainfall total after Sunday's storms.
It's already significantly wetter than last August, when just 0.20 inches of rain fell throughout the entire month.
Through July, DC has received 17.29 inches of precipitation this year, but the city has fallen short of its monthly averages in 11 of the past 12 months.
Since 2000, DC averages 25.27 inches of precipitation from January to August. The lack of precipitation has sent the area into a months-long drought.
