The beginnings of the secondary eyewall could be seen as early as last night even in the VIIRS day/night band image.

#Halong seems it was able to fit in a last-minute ERC. Approaching Hachijoujima and Aogashima now. Storm emergency warnings issued for the Izu Islands by JMA.

Expanding wind field from ERC + extratropical transition means outlying areas in east-central Honshu may also feel gale-force gusts.

Halong as seen last night from the VIIRS instrument aboard NOAA-20, with the left image showing a nighttime "visible" scan of the storm illuminated by the supermoon.

While I’m at the UCAR Member’s meeting, I’m reminding everyone of the internships, workshops, and other student opportunities that they have available! www.ucar.edu/exhibit/stud...

Of course the week this happens is when I’m giving the typhoon briefings for JMA. Gah

Hahaha oh jeeez

Halong rounding itself out nicely. Now equivalent to a Category 4 storm. Will have about 24 more hours surrounded by supportive conditions.

OTD in 2005: Short-lived Tropical Storm Tammy makes landfall near Jacksonville, FL. Though 10-15" (250-375mm) of rain fell in GA, damage was relatively minor. Tammy's remnants were later absorbed into a cold front that brought 10+" of rain to parts of the mid-Atlantic and New England. #wxhistory

This was our old neighborhood in Myrtle Beach after the rains around 10/5/2015. Had the same results the year after with Hurricane Matthew. FD had to deploy boats for medical emergencies in the neighborhood.

Interestingly, this paper argues Joaquin provided only a relatively minor source of moisture for the event, and that Joaquin's crucial role was the TC's outflow accelerating the upper-level jet via negative PV advection thereby enhancing synoptic-scale forcing.

Charleston, SC measured a maximum 24h rainfall of 11.5" (292 mm) on 10/3. The largest 5-day total was 26.92" (684 mm) in Mt. Pleasant in greater Charleston, while a station in greater Columbia recorded a 5-day total of 21.5" (546 mm).

Below video shows a satellite animation of the event.

This week also marks 10 years since the historic October 2015 South Carolina floods.

A nontropical low interacting w/ Hurricane Joaquin resulted in days of heavy rainfall along a stalled frontal boundary (with 1-in-1000-year totals in some areas), causing 16+ deaths and $2.7B in damages, per NOAA.

Stan was the 4th storm to make landfall in Veracruz and 5th named storm to hit Mexico that year. Parts of Chiapas may have observed over 500mm (20") of rain in 48 hours. Honduras and El Salvador were also hit particularly hard by the storm.

The name Stan was retired by the WMO the following year.

20 years ago today, Hurricane Stan made landfall in Veracruz, Mexico. Stan and its remnants caused catastrophic flooding & mudslides in parts of Mexico and Central America, w/ the UN estimating 1,500+ killed in Guatemala, making it indirectly the deadliest storm of the 2005 Atlantic season.
