Central PA: Watch for Sandy's Left Hook Next Week

Sandy will drive through the Caribbean the next few days. However, while Sandy could take the fight to Bermuda next week, there is still the danger of a last-minute left hook over Pennsylvania.

Chilly autumn weather is on hold this week in the northeastern United Staes and the tropics have become very active.

The period of consternation and concern for potential damaging and disruptive weather impacts in central Pennsylvania spans Monday to Wednesday of next week.

A hurricane or hybrid storm remaining well offshore would have minimal direct impact on Pennsylvania. Most likely, cool air and blustery conditions would sweep in with spotty showers in this scenario.

However, there is a danger of the storm being captured and pulled westward by another system approaching from the Midwest next week. Sandy would undergo a transition from a hurricane to a hybrid or non-tropical system, but the storm would retain every bit of a hurricane's intensity.

Such a left hook could not only bring the fight to the backyard, but could deliver a knockout blow.

If Sandy takes a left turn toward the mid-Atlantic next week, central Pennsylvania could wind up with heavy rain, wet snow and strong winds. Photos.com image.

As the storm crashes ashore with this scenario, hurricane-force gusts would sweep inland downing scores of trees and causing widespread power outages over New England and perhaps portions of Pennsylvania. While major river flooding is still not likely in this scenario, heavy rain combined with fallen leaves could lead to small stream and urban flooding. Heavy wet snow could fell on the mountains of central and western Pennsylvania in this scenario, adding to the potential for downed trees and power lines.

A third scenario allows Sandy to escape out to sea, but forms a new storm near the coast with more average nor'easter conditions in the region later in the period next week.
