People in Pennsylvania and surrounding states are being hit hard with damaging wind and flooding rainfall from Sandy.
In the Keystone state and over much of the Northeast, the storm will threaten lives and property and will bring widespread travel disruptions.
Sandy is making landfall between Atlantic City and Wildwood, N.J. and was driving westward. Sandy will push over southern Pennsylvania and northern Maryland late Monday night and Tuesday.
The effects from the powerful and massive storm will linger for days after the storm's demise.
Since Sandy is such a large storm in terms of surface area, effects will be more than a compact hurricane.
According to AccuWeather.com CEO Barry Myers, "Sandy is a hurricane wrapped inside a winter storm."
There will be major impact due to wind and flooding not only in the Harrisburg area, but as far north as portions of New England and as far south as Washington D.C. and Norfolk, Va. and as far west as the Great Lakes.
At this time AccuWeather.com meteorologists expect wind gusts in the neighborhood of 60 to 70 mph in southeastern and south-central Pennsylvania. Gusts this strong can down trees, power lines, send loose objects airborne and cause minor property damage.
Avoid walking or parking under trees as large limbs can come down with no notice.
The heaviest rainfall, a general 4 to 8 inches, is projected to fall over southern Pennsylvania to northern Maryland. Locally higher amounts are possible over a several-day period through Wednesday.
Enough rain will fall in the local area to raise the risk of flash, urban and stream flooding. Fallen leaves will block storm drains adding to the potential for street flooding.
AccuWeather.com meteorologists do not believe enough rain will fall to cause major flooding along the Susquehanna. However, a significant rise in the river level is likely this coming week with lowland and unprotected area flooding possible.
Farther south, since the arm of heaviest rain will aim across northern Maryland and the West Virginia Panhandle, a significant rise will occur on the Potomac River with the potential for major flooding during the middle and second half of this week.
After a period of above-average temperatures dominated most of the Midwest and Northeast during much of April thus far, a complete reversal in the weather pattern is evolving this week.
A new round of thunderstorms will bring the risk of severe weather across parts of Texas and Oklahoma to the lower Mississippi Valley by the middle of the week.
Due to the positive feedback, the National Weather Service has expanded their former, experimental Impact Based Warnings to include the Southern region for the spring of 2015.
As residents are far from over with the recent cold winter across the Great Lakes, Mother Nature will bring the return of snowflakes to the region this week.
Global warming and climate change, two terms that are treated synonymously in most media coverage and casual debate, have been shown to spark different reactions from the American public.
Following strong to locally severe thunderstorms in part of the South Central states at midweek, the risk of violent storms will increase over the region on Friday.
