FIRST ALERT WEATHER: Step-by-step tracking of storm expected to hit NH Tuesday night

CONCORD - Keep your rain gear handy! A cold front is pushing in from the west and colliding with a huge plume of tropical moisture head of it. Heavy rain currently in New York state will begin to spread into New Hampshire later this afternoon.
Rain will become heavier overnight with tropical downpours expected during the morning hours Wednesday.
Widespread rainfall amounts of 2-4" are likely which could lead to some street and small stream flooding. A few locations may even get up to 5" of rain.
The heaviest rain will be winding down by Wednesday night. A Flood Watch is up through Thursday morning.
Gusty NE winds will follow the rain with gusts to 30-35 mph at the coast. Seas will be building to 5-9 feet off the coast Wednesday night. Seas will build up to 8-12 feet by Friday.
Coastal Flood Watch is up through Thursday afternoon. We will have to watch the high tide happening early Thursday morning around 2 AM as tides are running astronomically high. Minor coastal flooding will be possible.
Meanwhile, all eyes are focused on Tropical Storm Joaquin. Currently 45 mph.
Our models are not sure of the exact path this storm will eventually take as there is a wide variety of solutions. The National Hurricane Center's track has this storm remaining off the east coast, but what is likely is the moisture from Joaquin will be directed back into the mid-Atlantic states and northeast.
This will add more rain on top of the heavy rain which will fall in the next 24 hours. This will likely help to create more flooding. Some areas will be ending up with 6-12" of rain by the end of the weekend.
A deep upper level trough will remain off the coast right into the start of next week which could keep the periodic heavy rain, with cool raw breezy conditions going right into next Tuesday!
Stay tuned as this is a very energized weather pattern, loaded with tropical moisture. In a worst case scenario we may be looking at dangerous flash flooding conditions developing if we get too much rain in too short a time.
