It looks like Isaias will be in one of its strengthening phases as it makes landfall, which will certainly pack more of a punch than if it were weakening.

[Okibeach]

Oak Island area is under the gun for a pretty significant tornadic threat. Well defined couplets coming onshore on the velocity scan.

Weather radio going off now.

expected it to regain hurricane strength so many times yesterday, looked at it around noon and figured it was finally never gonna get it back but it finally stacked up and got that gulf stream juice, good luck to all my old neighbors and friends in Myrtle

Landfall after landfall this season so far.

Pulling the same move Hanna did, shaky performance most of the way but a strong finish lol

Five named storm US landfalls including two hurricanes by the first week of August. Been quite a year already

[USTropics]

How far out do the strongest winds extend from the center of Isaias?

The strongest winds will remain in the NE quadrant. Here is the official guidance from NHC:


Here is the GFS forecast for winds:

32 mile wide eye per recon. My kids in Tidewater are blowing this storm off. Just a little wind and rain they say.....MGC

Plus Arthur that barely missed the OBX. Almost six of nine so far.

Lots of little hooks moving onshore around Oak Island and Bald Head. Waterspout and tornado threat increasing atm.

My DE hurricane history knowledge isn't as strong as it should be, but considering we got direct impacts from Fay and now almost certainly from Isaias, this might be our most eventful hurricane season ever by tomorrow night lol

Multiple possible tornadoes, thanks for the heads up!

I guess 2005 still has 2020 beat as the earliest date for two US hurricane landfalls, right? Because Cindy was upgraded to hurricane post-season and Dennis.

CC drop in a well-defined hook between Oak Island and Boiling Springs Lake. Quite possibly a waterspout came ashore and continued as a tornado.

Yup. Isaias could be our windiest event (tropical related) since Sandy. Lots of rain coming too. 2-5 inches in most of the state.

One confirmed and several other possible.

Wilmington/Myrtle Grove area needs to take note. Strong rotating cells will be coming on shore within the next half hour.

[invest man]

Looking at Wilmington radar appears either the eye is forming an inner wall or the 32 mile wide eye is tightening. What am I seeing? Looks like it’s continuing to move more toward oak island Wilmington area.

Kudos to pro Met Wxman. He called it this morning. Good job!

I thought it would weaken to about 60 MPH
