-Storm Surge (Gulf waters map below; GA/SC coast likely added to map Wednesday)
-Rainfall (WPC/NOAA map below; watch for heavy rainfall Appalachian mountains)
-Inland winds (fast moving storm = less time to wind down, tree/power issues far inland)
-Watch/Warning are time based issued, expect these to expand in time this week.

Hurricane John made landfall between Marquelia & Copala, Guerrero Mexico Monday night.

Sunset over #PTC9. Storms bubbling; general rotation. 23Sept2024

Hurricane John rapidly intensifies along the South Mexico coast. Still strengthening. Center only about 50miles(80km) offshore. Hurricane force winds are currently estimated to only reach 10miles(20km) from the center. Tropical Storm winds up to 45miles(75km) from center. 610pEDT/410pCST 23Sept2024

First official cone map for newly designated #PTC9
23Sept2024 11aEDT

**Shifts are possible as storm has not formed yet** But likely to come together in a hurry.

(Potential Tropical Cyclone Nine - “PTC” designation allows advanced lead time communicating hazards prior to storm actually forming).

First Hurricane Hunter flight to investigate #97L takes off 1030aEDT.
PTC designation likely coming soon to issue first NHC cone map, Watch/Warnings for Mexico/Cuba. Watches for US coast possible later tonight or by Tuesday.

Tropical Storm #John just off South Mexico coast in East Pacific. May slow down near the beach. There is a chance it reaches / nears hurricane status before moving along. Heavy rains to be pushed up, mainly East side with the onshore flow off the water. 23Sept2024 8aEDT/6aCST

Tropical Depression Ten-E forms about 180miles(290km) Southwest of Puerto Escondido, Mexico. Winds currently 35mph(55km/h). Likely named Tropical Storm soon. Heavy rainfall potential as slowly moves near the coast.
#TD10e 6pCST 22Sept2024

GFS and Euro(ECMWF) coming into better agreement on a central to east Gulf system later this week.
21Sept2024

Atlantic:
-Gordon remnants heading North may briefly develop again.
-Yucatan/Cuba area start of next week could spark something new to monitor.
18Sept2024 8pEDT

#PTC8 throwing heavy rain near Wilmington, NC. Gusty winds to 50mph or so may accompany. Tornado potential as well, mainly Northeast of storm center Eastern NC. Calmer on South side. Power/tree issues start around 40mph+/-. 735aEDT 16Sept2024

'Potential Tropical Cyclone 8' (formally invest #95L) along Carolina coast. Scattered showers next few days into the region. No surge warning as that typically starts at 3ft+, but still 1-3ft higher water level potential, beach erosion & rip currents. PTC designation started in 2017 for advanced lead time in hazards prior to storm actually forming. PTC8 15Sept2024

Invest #95L along Carolina coast. Regardless of any Sub/Tropical classification, the main impacts are rough beach conditions, gusty winds and heavy scattered rainfall potential next several days as moves inland. 15Sept2024

#ileana goes poof as enters extremely dry air mass. (image: 1145aEDT,845aPDT/MST 14Sept -> 830aEDT,2aPDT/MST 15Sept2024)

There's no win without the team #Gordon! Harmless low level cloud swirl outpacing storms to its East. Tropical systems like to be vertically aligned. This...isn't how a storm survives. Models in good agreement on turn North/Northeast by middle of the week. 8aEDT 15Sept2024

Tropical Storm #Gordon in the Eastern Atlantic running into a wall of dry air Friday evening. 13Sept2024

Tropical Storm Ileana entering the Gulf of California 13Sept2024

Friday the 13th in the tropics. 2024

#Francine now a Tropical Depression with 35mph(55km/h) winds. Some here or there tree/power issues but overall attention turns to rainfall(see map below for now to Sunday AM) & potential tornadoes(mainly FL panhandle, AL & West GA region with those classic rain tails). 12Sept2024 715aCDT

#Francine's Southern half missing on radar now as wind shear and land interaction help open core. Still watch for gusty winds even if no rain is present. 11Sept2024 820pCDT
