There's still some variation in the tracks of Sandy in a few different models, but the all center around Monday being the worst day for us.
Best case scenario - the storm tracks farther north hitting land somewhere in New Jersey and then moves northwest through Pennsylvania. Our rain totals would be significantly less inland and over southern VA. Winds could still gust around 40mph on Monday.
Worst case scenario - the storm takes a track farther south hitting land around Delaware/Maryland and tracks West inland. Wind gusts could be 50+mph inland, and 60+mph at the coast and in the Peninsulas.
Both the European and GFS models are shown below. Coastal areas should get ready for heavy rain as early as tonight. Most of the rain tomorrow could be along I-95 and east. You should have your preparedness plans finalized by this morning.
Either way, the Northern Neck and Middle Peninsula will likely see the biggest impacts. Winds will be stronger over eastern/northeastern Virginia than in central Virginia. Flooding is also a big concern for the coast as they could see 8 or more inches of rain by Tuesday. Flooding shouldn't be as much of a concern in central Virginia because it's going to be raining over a long period of time (not dumping all the rain at once on us), and river levels are low.
