Sunday 14 August 2017:
Long tracking invest "99L" that rolled off Africa's west coast some time ago has finally organized enough to become Tropical Storm Gert.

Will stay offshore bringing slightly higher waves this week to some US East coast beaches, main effect will be increased rip current threat.

5amEST Monday 14 August 2017:
Winds 45mph, moving NNW 9mph, pressure 1009mb. Could become a hurricane this week as it heads off into the Atlantic in the general direction of Iceland / northern Europe late this week / this weekend.

Official storm info while it retains tropical characteristics is released at 5/11 am/pmEST from the US National Hurricane Center (NHC): NHC

Satellite imagery/loops (taken every 30-min, with 25-min delay before posting): Satellite imagery

Other overall area satellite views can be found here: Atlantic Tropical Imagery

Microwave pass shows Gert may be trying to form an eye already:



Also storm may become a hurricane due to ideal postion with upper level winds/jet stream...sort of turbo charge it if you will:

11amEST 14 August 2017:
As above two images suggested Gert is quickly getting stronger. Winds 60mph, moving North 8mph, pressure 1002mb.

Rip Current info below:
Rougher surf and increased rip current threat will start arriving along NC and VA coast by this evening spreading north this week all along the US East coast. Just be more careful if you go in the water. Rip currents can fool many, causing the drowning of even experienced swimmers.

Sometimes these currents are obvious and sometimes not. There are a few tell-tale signs sometimes that can be seen such as:
-Can be found at/near piers or anything that sticks out into the water.
-a channel of churning, choppy water
-an area having a notable difference in water color
-a line of foam, seaweed, or debris moving steadily seaward
-Waves with small pockets of calmer waters/smaller waves at the break line. Calmer part looks the safest when in fact thats the rip current pulling water back out to sea making the waves smaller. Example:


-If caught in one swim parallel to the coast, then swim back towards shore. If you dont make progress back just swim parallel to shore more then try again. Drownings occur when swimmers keep trying to fight the current and tire out.

Gert seems to be blocking the front from moving off the mid-atlantic coast. Here in Central PA the forecast last evening called for sunny skies today. The clearing made it into western/northwestern PA but we are socked in the clouds this morning.

Appreciate your updates, even if no one responds!

Ha! Thanks! Ya, sometimes you never know when no one else says anything! I see the number of times read keeps growing so someones always around so I keep updating.

Actually the cold front combined with the subtropical ridge / Bermuda High (the blue H on weather maps!) over the Atlantic are forcing Gert up and out. Would have quite the storm on the east coast without them!

11pmEST Tuesday 15 August 2017 update: winds 85mph, moving NorthEast (away from land!) 15mph, pressure 979mb. Will hit cooler waters Wednesday evening/ early Thursday and quickly begin to weaken. Stays offshore of North America.

As mentioned in 2nd post of thread image from TropicalTidbits, the storm is reaching the jet stream which could serve to basically turbo charge the storm, makimg it stronger today. Reguardless, track doesn't change, stays offshore.
