  1. Anyone else noticing the NAM is dropping 16" of rain on the Appalachians in NC. Tropical Depression Fred dropped a similar amount just last August on the same area.
  2. While this isn't close to Sandy in size or strength, I do think with the duration and size of the wind field that the surge is being under forecasted. There could definitely be areas that see 6-8' of storm surge.
  3. Has anyone calculated the IKE for Nicole?
  4. How large is the TS wind field at that point?
  5. I think due to the size of the wind field that the storm surge in NE FL is being underestimated, 4 days of fetch coming onshore through multiple tide cycles during a "Beaver Tide" will push more water up the St Johns than anticipated, I feel it will be as high or higher than Irma in 2017.
  6. 991 Landfall at around Hobe Sound
  7. Euro coming in stronger, 995 at 48 hours edit, 993 at 60
  8. 833 WTNT42 KNHC 071458 TCDAT2 Subtropical Storm Nicole Discussion Number 2 NWS National Hurricane Center Miami FL AL172022 1100 AM AST Mon Nov 07 2022 The structure of Nicole this morning remains distinctly subtropical, as the low-level circulation remains tangled up with an elongated upper-level low. The wind-field also remains quite broad, with data from the NOAA-P3 Hurricane Hunters this morning showing the highest winds remaining displaced well away from the center. The initial intensity is being held at 40 kt for this advisory which is supported by the subtropical classification of ST2.5/35-40 kt from TAFB, the earlier scatterometer data, and recent SFMR winds from the NOAA-P3 aircraft in the 40-kt range. Nicole might be starting to take a northwestward turn this morning, with the estimated motion at 320/8 kt. A continued northwestward motion is expected through the day, though there might be some wobbles more north or west here and there as the low-level circulation continues to interact with the decaying upper-level low. After 24 hours, an anomalously strong mid-level ridge is expected to amplify over the southeastern U.S. which is expected to steer Nicole and result in the system turning westward or even west-southwestward on Tuesday night into Wednesday. This ridging will then re-position itself to the northeast of Nicole by Thursday and Friday which is expected to allow the cyclone to begin gaining latitude after it moves across the Florida Peninsula, though how quickly this occurs is a source of track uncertainty in this time frame. Finally a broad mid-latitude trough is forecast to eject out of the Rockies into the Great Lakes region, further eroding the ridge and allowing Nicole to recurve by the end of the forecast period. The track guidance is fairly tightly clustered for the first 60 hours of the forecast, though it has taken a noticeable shift southward this cycle, and the NHC track forecast was shifted a bit southward due to this adjustment, but still is a bit north of the HFIP Corrected Consensus Approach (HCCA). Intensity wise, Nicole may take some time to consolidate given its large radius of maximum winds and currently meager central convection due to nearby dry air related to the nearby upper-level low. This feature should gradually decay and warm 27-28 C sea-surface temperatures should enable more organized convection to develop while the system remains in a low vertical wind shear environment. Nicole is forecast to transition to a tropical storm sometime in the 24-36 hour period as this convection helps to contract the radius of maximum wind, with further intensification expected thereafter. The intensity guidance was a bit higher this cycle, and the latest forecast now takes Nicole to a 65-kt hurricane in 60 hours, which is close to the latest HCCA, HMON, and SHIPS guidance. After Nicole moves inland, weakening is anticipated, and the region that Nicole is forecast to emerge off in the northern Gulf of Mexico has cooler SSTs that likely would not support robust reintensification. Regardless on the ultimate intensity of Nicole, the storm's large size due to an enhanced pressure gradient north of the storm will likely cause significant wind, storm surge, and rainfall impacts over a large portion of the northwestern Bahamas, Florida, and the southeastern coast of the United States during much of the upcoming week. Key Messages: 1. Hurricane conditions are possible across portions of the northwestern Bahamas and southeast to east-central Florida beginning Wednesday, where a Hurricane Watch has been issued. Tropical storm conditions are possible in the Tropical Storm Watch areas in Florida and Georgia beginning Wednesday. 2. A dangerous storm surge is possible across portions of the northwestern Bahamas, much of the east coast of Florida and portions of coastal Georgia. A Storm Surge Watch has been issued for most of the east coast of Florida and portions of coastal Georgia. 3. Do not focus on the exact track of Nicole since it is expected to be a large storm with hazards extending well to the north of the center, and outside of the cone, and affect much of the Florida peninsula and portions of the southeast U.S. 4. Nicole will produce heavy rainfall by Wednesday night and Thursday across the Florida Peninsula. Flash and urban flooding will be possible across portions of the Florida Peninsula along with river rises on portions of the St. Johns River.

  9. NHC now predicting this to attain hurricane status
  10. Average intensity seems down this morning across models, but also further south approach and swing into the gulf seem to be very plausible
  11. Only 2 of the 50 Euro members have formation of any type in the Caribbean
  12. Its the price you pay to live in paradise, people will not give up ocean front views (or gulf front), even if they do, real estate vultures will come in and buy it all.
  13. It honestly gets a little worse every day right now, traffic is obscene getting on and off Estero Island. Typically takes 3 hours to go 15 miles from Fort Myers city to FMB and 2 hours to get back off the island, debris piles are high and until they are somehow able to open the east end bridge towards Bonita Beach, it will stay that way. I was there again yesterday.
  14. I spoke with he and Jeff Evans yesterday at a property in Fort Myers Beach.
  15. Cape Coral was designed this way, it is 3 feet above sea level.
  16. Looks like it it back on course with the NHC, just a little to the east after the earlier wobble
  17. Charley was a small diameter storm, 5 mile wide eye with a forward speed of 26 MPH, this isn't Charley,
  18. Pressure dropping on Euro at 144, high locked above, looks like its going for the 1-2 punch.
  19. Has anyone else ever read over this before? http://gtbacp.com/presentations/Project_Phoenix_Scenario_Info.pdf
  20. Was written in Jan 2010, but path looks similar.
