The National Weather Service has issued several warnings and watches for our area as Sandy approaches.
The Weather Service Sunday morning issued a high wind warning, a coastal flood warning and a flood watch.
High Wind Warning
The high wind warning could produce damaging winds across our region Monday and especially early Monday night. Sandy will again become a powerful storm as it turns west Monday slamming into the northern mid-Atlantic coast late Monday evening with a period of 60 to 75 mph wind gusts.
The high wind warning in effect from 8 a.m. Monday to 9 a.m. Tuesday.
Winds northeast to north at 35 to 45 mph with gusts of 60 to 75 mph are anticipated. Shifting winds may still gust to 55 mph Tuesday morning before diminishing later in the day. The strongest winds are expected to occur between 4 p.m. Monday and 4 a.m. Tuesday.
A prolonged period of high winds will increase the potential for structural damage. Downed trees and widespread power outages especially from the I-95 corridor eastward to the coasts. The combination of the wind, increasingly rain softened ground and many trees still loaded with leaves should result in widespread power outages Monday and Monday night. Trees could be completely uprooted and many tree limbs will be broken. Power outages may be of long duration.
There is a small chance this warning may need to be extended into midday Tuesday dependent on Sandy`s strength and location in Pennsylvania.
You should continue to monitor the latest forecasts. and secure or bring in items that could be tossed around in the high winds.
Coastal Flood Warning
The Weather Service also issued a coastal flood warning from 8 p.m. this evening to 4 a.m. Tuesday for the tidal Delaware River.
According to the warning, moderate coastal flooding is possible along the river during the Sunday night, Monday late morning to afternoon and Monday night high tides.
Numerous roadways may flood and moderate property damage is possible with rainfall of 5 to 10 inches forecast during the period. Heavy rainfall near time of high tide will force considerable small stream runoff into the tidal Delaware and exacerbate tidal flooding.
Be prepared for rising water levels and take appropriate action to protect life and property. Do not drive your vehicle through flood waters. The water may be deeper than you think. You will be putting yourself in danger and your vehicle may be damaged...leading to costly repairs.
There is also a flood watch in effect through Tuesday afternoon. Substantial flooding is likely in portions of our area especially from southeast Pennsylvania
Heavy rains probably begin sometime today or tonight. The worst will be tomorrow and tomorrow evening when torrential downpours can produce one half to 1 inch rains for several hours throughout the flood watch area.
Small stream flooding as well as considerable urban and poor drainage flooding is expected to develop Monday morning and last well into Monday night. Larger main stem river flooding should follow by Tuesday even as the heavy rains have abated with Sandy`s westward passage into Pennsylvania. Leaves will tend to get washed into storm drains, which will enhance localized flooding.
Those living in areas prone to flooding should be prepared to take action should flooding develop including following detours and living comfortably with substantial travel inconvenience due to flooded roads.
