At least it keeps it fairly weak. I can't imagine that this system would have enough time to rapidly intensify.
It has a week to get it together.....we watched Isaias and Hanna escalate in less than 24 hours.....it wont be a beast, but could definitely be destructive....

RI would be good in this case because it would send it north-east off the outerbanks with little impact inland. A tropical storm would flood western NC on that track so let’s hope for RI.

Not to leave off the low SW of Bermuda, these 3 (NC, SC, just offshore FL) on hour 132 of the 12Z EPS are from that:

This one is tough. Major models like the GFS/UKMET/Euro and even the genesis happy CMC continue to do very little with this (just keeping it a low level trough) while the ICON and a few EPS members go up to a TS. Currently, the satellite loops show very little with no more than a sheared naked low level swirl moving W. The local NWS offices are going with little development. We'll see.

Everything floods Wilkes County in your mind. I’m surprised you haven’t screamed about morning dew creating a mudslide in Wilkesboro.

Again, the Euro has very little. What is does have, a very weak sfc low, goes to just offshore SC but it then stalls just offshore.

Everything except Laura flooded Wilkes. When you have multiple record setting years of rainfall like hickory and nearby it’s prone to flooding with each system

This reminds me of hurricane Alex in 2004. It was not much to look at and no one expected it to do anything even when the NHC put out its first advisory.


ZCZC MIATCDAT1 ALL
TTAA00 KNHC DDHHMM
TROPICAL DEPRESSION ONE DISCUSSION NUMBER 1
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
5 PM EDT SAT JUL 31 2004

THE LOW PRESSURE AREA OFF THE NORTHEAST FLORIDA COAST HAS SHOWN
INCREASING CONVECTIVE ORGANIZATION THIS AFTERNOON...WITH SATELLITE
INTENSITY ESTIMATES OF 30 KT FROM TAFB AND 25 KT FROM SAB. THUS...
ADVISORIES ARE BEING INITIATED ON THE SYSTEM AS TROPICAL DEPRESSION
ONE WITH 25 KT WINDS. WHILE THE DEPRESSION HAS A LARGE CYCLONIC
ENVELOPE...THE CENTER WAS VERY POORLY DEFINED ON THE RECONNAISSANCE
FLIGHT THIS MORNING...AND IT WOULD NOT BE A SURPRISE IF THE FLIGHT
SCHEDULED FOR 0000Z FINDS THE SAME.

THE INITIAL MOTION IS A SOMEWHAT UNCERTAIN 315/8. THE DEPRESSION IS
CURRENTLY BEING STEERED BY THE WESTERN END OF THE SUBTROPICAL
RIDGE...WHILE WATER VAPOR IMAGERY AND LARGE-SCALE MODELS SHOW
DEEP-LAYER TROUGHING OVER THE CENTRAL UNITED STATES MOVING EASTWARD.
ALL GUIDANCE SHOWS THE CYCLONE RECURVING NORTHEASTWARD AHEAD OF THE
TROUGH...WITH THE BIGGEST DIFFERENCES IN THE GUIDANCE BEING HOW
FAST IT MOVES AFTER RECURVATURE. THE OFFICIAL FORECAST TRACK WILL
CALL FOR THE SYSTEM TO TURN NORTHWARD AT ABOUT 24 HR AND
NORTHEASTWARD AFTER 36 HR...BRUSHING THE SOUTHEASTERN U.S. COAST.
WHILE THE OFFICIAL TRACK CALLS FOR LANDFALL IN NORTH CAROLINA...
SEVERAL MODELS RECURVE THE CYCLONE SHARPLY ENOUGH TO KEEP THE
CENTER OFFSHORE.

THIS LARGE AND POORLY DEFINED SYSTEM WILL LIKELY TAKE TIME TO
CONSOLIDATE EVEN THOUGH CONDITIONS GENERALLY APPEAR FAVORABLE FOR
INTENSIFICATION. THE INTENSITY FORECAST THUS CALLS FOR SLOW
STRENGTHENING UNTIL THE SYSTEM REACHES THE COAST. WHAT
INTENSIFICATION MAY OCCUR AFTER THE CYCLONE CLEARS THE U.S. EAST
COAST IS QUESTIONABLE...AS THE LARGE SCALE MODELS DISAGREE ON
WHETHER IT WILL DISSIPATE OR STRENGTHEN DURING INTERACTION WITH THE
WESTERLIES. FOR NOW...THE INTENSITY FORECAST WILL COMPROMISE
BETWEEN THE TWO EXTREMES AND KEEP A STEADY 40 KT UNTIL
EXTRATROPICAL TRANSITION.

THE PROXIMITY TO THE COAST REQUIRES A TROPICAL STORM WATCH TO BE
ISSUED FOR PORTIONS OF THE COASTS OF NORTH AND SOUTH CAROLINA AT
THIS TIME. A TROPICAL STORM WARNING MAY BE REQUIRED IN A LATER
ADVISORY.

FORECASTER BEVEN

They forecast it to maybe make it to 40 mph before moving quickly NEand dissapating. Turned out to be a 120 mph cat3

Only one Happy Hour EPS member gets down to below 1004 mb and it heads toward the abode of @pcbjr although fortunately it is not that strong (at or over 1000 mb). Those on the right are from Paulette:

1. An area of low pressure is located about 300 miles west-southwest of
Bermuda. Showers and thunderstorm activity associated with the low
has increased since last night, but remains somewhat disorganized.
Gradual additional development of this system is possible during the
next two or three days and it could become a tropical depression
while it moves slowly westward to west-northwestward. Interests
along the southeast coast of the U.S. should monitor the progress of
this disturbance.
* Formation chance through 48 hours...low...30 percent.
* Formation chance through 5 days...medium...40 percent.

This feels like Hanna, except in this case NHC has decided to watch...

Time for obs thread? up to nearly a 100% chance based on the models for 1-3” rain bands to start moving in late tonight from the eastern OBX all the way to the blue ridge mtns. The system is bringing tropical moisture for all as seen on NAM and nearly all short term guidance for this week and I believe any stronger cells could produce flash flooding with 1-2” rates.
