So what is really happening?

We know that what was the energy that NHC named Nicole is not going to be moving up the east coast. However, moisture from what was a monsoonal trough of low pressure will be entrained into a developing area of low pressure around the Carolina coast.

This developing area of low pressure will lift off to the NE following the front that it has developed off of. Moisture from down south will continue to train up the east coast ..providing copious amounts of rainfall.

There will also be some gusty winds but this has nothing to do with any tropical system but rather the approaching low pressure area and the high pressure that will be dropping down into the region. So its the difference between the high pressure and the low pressure gradient that will be creating these gusty winds-not anything tropical.

Flooding will become and issue because the rain may come down so heavy at times that it will run off..instead of just saturate into the ground.

This is what the current thinking is for rainfall..

Indeed it is very possible that the area of MD that is in 2-4 inches could very well fall into the category of 3-6 inches.

Be careful if you are out and about travelling and come across any standing water. Do not attempt to cross as you do not know how deep it could be.
