I hope people are making preparations. Sandy is once again a hurricane and should strengthen a bit more as it travels north. The current track from the NHC has her making landfall around DE and moving west into Cecil and Harford counties as it then turns into PA. But, as I have been saying, do not watch the track of the center; winds and rain extend hundreds of miles out from the center.
As Sandy moves up the coast she will merge with (phase) the arctic low causing some strengthening as she tracks across land. In a typical hurricane landfall they lose their power since power for a hurricane comes from the moisture it sucks into itself. But in this case, the power will be transferred from the tropical moisture to the strength of the arctic low.

I do not wish to hype nor panic people about this situation but this is serious. The conditions we will feel in MD will be somewhat greater than what we felt from Irene last year and will last a lot longer than did Irene. Maryland will be impacted by Sandy as she parallels the coast and again as she travels inland along the MD/PA line. This event can last at least 3 days!
TIMING: We all will begin to have rain Sunday morning from the outer bands. Southern MD will start to see tropical storm force winds and greater early Monday morning into Tuesday while Central MD will feel the tropical storm force winds early Tuesday morning into Wednesday The closer you are to the center (eye) the strongest you will experience the winds.
WIND: We should see sustained winds in the 40s mph and greater over a couple days. Gusts can be above 70 mph.
RAIN: Depending how close you are to the center, we could see close to a foot of rain.
SNOW: Most of the snow should stay to the west of us, although the temps with the arctic low will drop into the 40s in the day and 30s at night, so Southern and central MD could see some flakes flying around, but snow is not our major issue.
THREATS: Greatest threats are the wind and rain. Localized flooding is probable, although storm surge unlikely. Trees and power lines will more than likely come down.
A Flood Watch has already been issued. I expect to see many watches/warnings to be issued as Sunday progresses. I will keep you posted. Follow me on Twitter (www.twitter.com/wxmanmd) and my Weather Phone is updated with watches/warnings. Feel free to leave me messages with questions or storm reports: 443-470-9804.
