Florence and Isaac - FLHurricane.com

4PM Update 16 September 2018

Slow moving Florence continues unleashing Harvey-like rainfall over much of North and South Carolina, breaking the all-time record for tropical cyclone rainfall in at least North Carolina, and closing in on even national records.

As of 10AM, Wilmington had set an all-time annual rainfall total, at 86.79" (with several months yet to go). The previous annual record for the city was 83.65" set way back in 1877.

Current flood situation has 8 rivers at Major Flood Stage, 8 at Moderate. By Wednesday the forecast is calling for an additional 15 (23 total) rivers in Major Flood Stage, and an additional 5 in Moderate (13 total).

North Carolina transportation authorities continue advising road travelers to go around the state entirely.

Elsewhere, the remnants of Isaac are being tracked as an Invest (no new Invest number, keeping the same name). This area of disturbed weather has continued to show some signs of organization despite a less than ideal environment for redevelopment, and interests in the northwest Caribbean may want to keep watch. Pockets of heavy rains and gusts to tropical storm force are already occurring.

95L has pushed into northern Mexico, after helping deluge parts of coastal south Texas. Joyce and Helene are becoming more fully post-tropical at high latitudes near the Azores.

7AM Update 13 September 2018

Florence looks a bit weaker since last night, but the south side has actually improved overnight, setting it up to maintain or strengthen itself up to landfall, forward motion will begin to slow down today as it approaches the Carolinas. All preparations should have been finished yesterday, as conditions will gradually worsen in the warning areas today, and worsen quickly in the evening.

6PM Update 12 September 2018
Florence has weakened to a category 3 storm today, but the wind field has greatly expanded, meaning the big issue will be the storm surge. Large wind fields and strong winds create a massive set of issues, and will cause rivers to pile up or flow backwards in some cases at times.

Also Subtropical Storm Joyce has formed in the North Atlantic, no threat to land, but currently 4 active Atlantic systems, we could potentially have 5 with the other areas in play.

11PM Update 11 September 2018
Tomorrow, Wednesday, is the last full day to prepare in North and South Carolina. Use it wisely.

Florence is still a major Category 4 hurricane heading west northwest, tomorrow it will move the fastest then slow down as it approaches the coast on Thursday, do not focus on the exact track, but beware anywhere in the cone could feel hurricane force impacts either from wind, rain, surge, or all 3.

If local officials asked for you to evacuate, please do so.

** It is important for folks to realize that significant impacts extend well away from the center of Florence, and serious hazards such as a dangerous storm surge and flooding rains will cover a large area regardless of exactly where the center moves and that there is here is substantial uncertainty in the 3-5 track forecast..**

For information for your particular area pay attention to local media and officials.

9PM Update 11 September 2018
Some interesting changes today with the models, but otherwise the forecast track remains the same. Because of the uncertainty those who have evacuation orders should heed them, even in South Carolina as things could change quickly for you there, but the entire warning area should prepare.

Florence's eye and structure has expanded today, and recon will soon find if the strength has gone up or not . Storm Surge is likely a massive threat with this hurricane for many areas as it is expected to slow down forward motion right before landfall.

Original Update
A Storm Surge Warning has been issued from South Santee River, South Carolina, to Duck, North Carolina, and the Albemarle and Pamlico Sounds, including the Neuse and Pamlico Rivers.

A Hurricane Warning has been issued from South Santee River, South Carolina, to Duck, North Carolina, and the Albemarle and Pamlico Sounds.

A Tropical Storm Watch has been issued from north of the North Carolina/Virginia border to Cape Charles Light, Virginia, and for the Chesapeake Bay south of New Point Comfort.

Florence still approaches, and it appears somewhere near the SC/NC border with the potential to go south toward Charleston OR up to the outer banks as a large category 4 storm Thursday night or very early Friday morning and then potentially slow down. Therefore: A Hurricane Watch has been issued for the east coast of the United States from Edisto Beach, South Carolina, northward to the North Carolina-Virginia border, including the Pamlico and Albemarle Sounds.

Since the threat of storm surge with such a large, powerful hurricane is extreme: A Storm Surge Watch has been issued for the east coast of the United States from Edisto Beach, South Carolina (Just orth of Hilton Head Island) northward to the North Carolina-Virginia border, including the Pamlico and Albemarle Sounds.

In Hawaii Olivia has Tropical Storm Warnings for the majority of the sate, including Oahu and islands east, and Watches for the islands west of there.
