You can’t see it yet but a new coastal storm, a typical Nor’easter, is going to form off the Carolina coast tomorrow and track roughly parallel to the Eastern Seaboard and bring with it an increase in wind, rain, inland snows and a coastal storm surge.
All of the regional NWS offices are talking about the storm in their forecast discussions and it looks as though the areas hit hardest by Sandy will again be lashed by this system.
So far, the rain fall looks to be minimal enough to preclude any concerns about inland flooding. The heaviest rains will likely be near the coast which makes sense considering that this is a coastal storm and is not forecast to cross the coast or make a landfall. However, with many homes and businesses sustaining roof damage during Sandy, this rain is a serious issue and could cause further damage. If there is any chance to tarp open roof damage areas, now is the time to get it done.
Wind speeds will also be highest along the coast with gale force winds almost a certainty. From what I have seen, some of the strongest winds will be felt along the New Jersey and New York coasts with winds approaching 60 mph in gusts. This will be more than enough to knock the power back out for people who have recently had it restored. Here too, make sure any preparations to keep warm in case of power loss needs to be done now. Ask local relief agencies for battery powered lights and extra blankets today. The infrastructure is more vulnerable right now and it won’t take much to bring down additional trees and plunge large areas, especially near the coast, in to darkness once again.
Storm surge from extra-tropical storms such as this one can cause moderate tidal flooding which can extend in to back bays along the coast. Sadly, hurricane Sandy removed much of the protective dune system which will allow for more over wash and surge to reach in to some coastal towns. We could be looking at anywhere from two to four feet of flooding but a lot will depend on the track of the low and the duration of the long fetch of wind across the western Atlantic. A faster moving storm would be better, obviously. Again, from what I have gathered by reading the various NWS discussions, it looks as though the Wednesday night high tide will be the one of most concern – especially along northern New Jersey and some areas of Long Island.
As I have mentioned numerous times, utilize your local NWS info by going to weather.gov and inputting your ZIP Code. Read the content of the “Hazardous Weather Conditions” if the local office has put one up for the current storm. Here you will find more detailed information about timing and expected impacts to your local area. Keep in mind this is written by people in your region, not by a computer or from a cable TV news source. I highly encourage the use of the NWS local products, especially when it is important to understand the local impacts of a storm like the pending Nor’easter.
Luckily, the tropics are quiet with absolutely no areas to be concerned with in the coming days. We are nearing the end of a very busy hurricane season that will be remembered for generations to come because of Sandy and its legacy. For the people who are going through the painful and slow recovery process, hang in there. A lot of people are working to provide assistance for what is an overwhelming disaster. This current storm will be a set back for some, but it will not be nearly as intense or widespread as Sandy. That being said, it needs to be taken seriously and precautions taken to prevent further loss of life and even more damage to property.
I’ll post more here tomorrow morning with more specifics about what to expect as the storm begins to develop off the North Carolina coast.
