10:15 a.m. — Flood warnings in effect for Potomac River

The storminess since Friday is resulting in high water on area rivers. Flood warnings are in effect for portions of both the tidal (lower) and upper Potomac River.

On the tidal Potomac, the potential flooding is due to winds pushing water toward the shore as well as stormwater coming downstream; the flood risk is highest around high tide.

Here is the advisory and warning information for the District:

  • A coastal flood advisory is in effect from 11 am to 10 pm today for up to one foot of inundation above ground level.
  • A coastal flood warning is in effect for one to two feet of flooding from 10 pm tonight to 6 am Monday.
  • Shoreline flooding is anticipated “along portions of the seawall adjacent to Ohio Drive and the Hains Point Loop Road, and near the Tidal Basin and Jefferson Memorial,” according to the National Weather Service. Water may also “begin to bubble up through storms drains near Washington Harbor” in Georgetown, the Weather Service said, and the harbor will flood if “floodgates are not in place.”

Coastal flood warnings and advisories are also in effect for shoreline areas of St. Mary’s County in Southern Maryland into Monday.

Because of all the recent rain, flood warnings are in effect along much of the upper Potomac River northwest of the District, including for Little Falls and Point of Rocks until tonight.

A flood warning is also in effect for the Monocacy River near Frederick, Md. until 7 pm

A somewhat subjective rating of the day’s weather, on a scale of 0 to 10.

5/10: A Mother’s Day under a cozy blanket may be a good idea with cloudy skies, lingering dampness, highs in the 50s and a cool breeze.

  • Today: Mostly cloudy, cool, breezy, spotty shower. Highs: low to mid-50s.
  • Tonight: Mostly to partly cloudy. Lows: upper 30s to mid-40s.
  • Tomorrow: Becoming mostly sunny, still breezy. Highs: low to mid-60s.

A slow-moving area of ​​low pressure continues to blanket us with mostly cloudy skies, maybe a few lingering, spotty showers, and very cool temperatures for this Mother’s Day. Overall, it’s a drier day than the past two days despite the lingering dampness. Sunshine returns tomorrow with a gradual warming trend through midweek.

Today (Sunday): Mother’s Day weekend ends on a drier note compared to the past two days. But we could still see some spotty showers or patchy drizzle. Mostly cloudy skies help keep us unseasonably cool, with 40s this morning and afternoon highs struggling to the low to mid-50s. Northerly winds are breezy, with likes near 25 mph. Brightening skies or even a few peeks of sunshine are possible late in the day. Confidence: medium-high

Tonight: Mostly cloudy early but turning partly cloudy later in the evening and overnight. Winds diminish just a bit, but still with a lingering breeze from the north. Lows drop to the upper 30s to mid-40s. Confidence: high

Tomorrow (Monday): A few clouds early, then becoming mostly sunny. We warm into the low to mid-60s, which is still 10-15 degrees below average. Breezy northerly winds continue. Confidence: medium-high

Tomorrownight: Evening temperatures fall back into the 50s under mostly clear skies. Overnight lows trend a bit milder as they settle in the mid- to upper 40s. Confidence: high

looking good Tuesday and Wednesday, with partly to mostly sunny skies and warm temperatures. Tuesday highs should get to the upper 60s, followed by Tuesday-night lows in the upper 40s, and then wednesday highs in the comfortable low 70s. Be sure to apply sunscreen if you plan to spend time outdoors, maybe planting the garden? Confidence: medium-high

Some models bring the same area of ​​low pressure that soaked us this weekend back around toward us by next weekend, after hanging out off the coast during the week. That’s a long way off, and a lot could change. We’ll keep you posted.
