WHEN WILL ISAAC REACH THE DC AREA?, TROPICAL STORM LESLIE UPDATE - BETHESDA WEATHER FORECAST

The big question has been, will the remnants of Hurricane Isaac hit Bethesda, and if so, when?

The center of Tropical Depression Isaac is currently over Ohio.  Some outer clouds and precipitation associated with Isaac may reach us later today, but the heavier rains will come Tuesday.  My Bethesda Forecast below will have more specifics of what to expect throughout the day.

One piece of good news, is that the National Hurricane Center has again adjusted the amount of rainfall Isaac is expected to drop on the DC area, from 2" to 1.75" over the next few days.  Assuming no stallouts in the atmosphere, that should reduce the risk of local flooding.

As Isaac moves closer to the Mid-Atlantic tonight, rains will become heavier into tomorrow.

LESLIE UPDATE

Leslie has again declined to strengthen into a hurricane.  In fact, its winds have dropped to 60 MPH!  The bad news is that Leslie has slowed almost 50%, which will allow it to strengthen as it enters warmer waters.  However, the National Hurricane Center says it does not expect Leslie to strengthen today or Tuesday.  If you're reading this in the northern Leeward Islands, Puerto Rico or the U.S. Virgin Islands, Leslie is passing you by, but be alert for swells and rip currents at local beaches.

LOCATION:  610 miles SSE of Bermuda

WINDS:  60 MPH

MOVING:  NNW at 8 MPH

BETHESDA FORECAST

Your umbrella is still your best friend today!  This morning, it will be mostly cloudy, with patchy fog and some showers.  After 11 AM or later, showers and thunderstorms.  There is a 70% chance of rain, with cloudy skies the rest of the time.  High 82, 6-9 MPH breeze.

Tonight, cooler and cloudy, with a 5-7 MPH breeze.  Thunderstorm possible before midnight, and showers possible after midnight.
