Noel, before deciding to pay us a visit tomorrow, vacationed in the Bahamas, where the storm dropped copious amounts of rain - making driving a bit tough.

Category 1 Hurricane Noel is currently racing up the East Coast while undergoing a transition from a tropical system (warm core, no fronts, small radius of strong winds) to a baroclinic extratropical low (cold core, warm and cold fronts, large radius of strong winds). I know, I know, technical stuff.... so I'll break it down for you.

As Noel loses tropical characteristics, it will grow in size, and it's area of strong winds will expand outwards from the center. This means that although the CENTER of the storm WILL NOT make landfall, the strong winds and heavy rains will extend sufficiently far from the center of the storm to bring us some nasty conditions tomorrow.

Because Noel will no longer be a hurricane by textbook definitions, hurricane warnings have not been issued for our area. This is only a technicality. The Cape and Islands will most likely see strong tropical storm to hurricane conditions tomorrow, with sustained winds of 50-60 mph and gusts possibly as high as 85 mph! Yikes!

Further inland, places like Lowell will see strong winds and heavy rain, although to a lesser extent than coastal areas. Right now, 30-40 mph sustained winds appear likely for our area, with gusts possibly as high as 50 mph.

Because of this, the National Weather Service has issued a HIGH WIND WARNING for most of eastern Massachusetts from 6 am to 9 pm Saturday, including the Lowell area. The message from the NWS is below:

Exciting stuff huh? Well, it is to us meteorologists at least. To sum it up, the effects from Noel include:

Wind Gusts up to 60 mph (85 mph Cape)
Downed Branches/Trees/Power lines
1-4 Inches of Rain
Localized Street Flooding
Battering Waves Along the Coast of up to 30 Feet
Beach Erosion
Coastal Flooding

The good news - Noel will be racing to the NNE and as a result, we won't feel the effects for all that long. It all looks to be out of here by late Saturday night, with the height of the storm occuring from 11am-4pm.

Thereafter, Noel has his sights set on Canada. The storm will continue to intensify as it races to our north.

We will have additional updates as conditions warrant.
If you haven't yet secured objects outside, do so now!
