Moisture continues to stream up ahead of Hurricane Helene. This will exacerbate tree / power issues once high winds move inland this week as well as flooding concerns. 705pEDT Wed 25Sept2024

Heavy scattered rainfall from Tuesday into Helene's passage later this week is expected to lead to over a foot of rainfall in some regions in the Appalachian mountains of GA, SC, NC. Hurricane's bring multiple far reaching impacts. Be prepared! 24Sept24

Filling in the gaps. #Helene

'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
