Fascinating loop, ( focus on the second loop not the first) , espcially if you run it and pause it. 

I like to look at the end of the run/ loop,  at that feature moving across Canada, and into the Northeast.  Rather robust at that range.

Those rip currrents are serious stuff.  Just read about a 50-year old guy and his 28-year old son both lost to a rip at the NC coast.  Terrible.

 

FYI.  From Accuweather feed: 

Water temperatures were close to the peak for the year and were inviting in all of those places. As of Thursday, the ocean temperatures off the Outer Banks were 84.2 degrees Fahrenheit. The water temperature at beaches in Atlantic City was 79.0 F, 74.3 F in the waters off Montauk and 75.6 F near Nantucket. However, AccuWeather forecasters warn that dangers such as rough surf and strong rip currents will be a concern through Saturday in this zone.

A 50-year-old father and his 28-year-old son were killed in a rip current near the Oak Island Pear in North Carolina on Wednesday afternoon, according to WECT. Bystanders pulled the father from the water, but emergency responders were unable to save him. A two-hour search ensued for his son, who was still missing, but his body was later recovered.

According to data from NOAA, more people have died as a result of rip currents on a yearly basis over the last decade than from lightning strikes or due to impacts from extreme cold combined.

Looking at the surf zone wave models currently, it appears that some legit surfing potential for those experienced enough will occur this weekend along the New Jersey and Delaware beaches. Of course I favor the NJ beaches because decade long beach repleneshmnet  along the DE beaches has caused more of a shore break to occur.  

Wave modeling indicating 5 Foot waves with a period of 14 seconds arriving from the SE on Saturday with a more West wind off the land on Sunday .     

Still iffy though on the exact wave forecasts,  as the various wave models are still in a bit of disagreement. 

 

 

 

 

Yeah, really sad what's happened to the Delaware beaches and OC because of beach replenishment. I remember growing up as a kid with so many fond memories of boogie boarding waves in Ocean City, sandbars way out into the ocean, etc. All of that is gone now, and I'm not sure if and when it will ever come back. Went to OCNJ a few years back and the waves there were great and didn't crash right on the beach.

Thats why I go to Wildwood.  The reason is two fold, the man made grade used is much steeper,  versus natural beach slopes, and the quality of the source is different meaning they used pebbles at one time mixed in.  

 

This is a good link.

Here is a look at generated wave heights with the storm this weekend.
