Tropical Storm Isaac may have changed the schedule for the Republican National Convention, but forecasters said it's not likely to have an effect on the D.C. area for days, if at all.

The storm is predicted to make landfall in Louisiana or Mississippi early Wednesday morning and travel up the Mississippi River valley toward St. Louis, said Andrew Woodcock, a meteorologist with the National Weather Service in Sterling.

Still, the D.C. area may not be immune to flooding and wet weather this week.

The National Weather Service has a coastal flood advisory in effect through 8 a.m. Tuesday in parts of the D.C. area -- including the District, Arlington and Alexandria. Minor flooding is possible along the waterfront, Woodcock said.

Monday, isolated showers are possible. The high temperature at Reagan National Airport is expected to be about 86 degrees.

Tuesday could also be rainy, and thunderstorms are possible after 11 a.m. Forecasters are predicting a high temperature at the airport of about 89 degrees, making it the warmest day of the week.

After that, the rest of the week is expected to be rain-free. For Wednesday through Sunday, forecasters are predicting sunny or mostly sunny weather in the D.C. area, with high temperatures in the mid-80s.
