Potential Tropical Cyclone (PTC-9) & Major Hurricane Humberto Update – Saturday 9/27/25 at 920 AM EDT/1320 UTC
Hello to all…
The VoIP Hurricane Net Management Team is monitoring Potential Tropical Cyclone (PTC-9) and Major Hurricane Humberto for potential net activation as we get to the early to middle part of next week. There remains considerable uncertainty especially with PTC-9 and its track toward the Southeast US coast.
Starting with PTC-9, this area of disturbed weather is becoming better organized and will likely become Imelda later tonight or Sunday as it tracks north-northwest through the Bahamas towards the Southeast US Coast off the South Carolina and Southeast North Carolina coast. Tropical Storm Warnings are in effect for much of the Bahamas. From there, the forecast is highly uncertain with a number of models stalling the system off the coast and even tracking it straight east with no landfall to the coast though winds and heavy rainfall would affect the coast before the eastward turn. Other models take it to a landfall on the South Carolina coast while still other models stall it for several days and then have a landfall on the US East Coast between South Carolina and the Delmarva. The track differences will likely not be resolved for another 1-2 days and we will monitor the progress of the system closely including monitoring all forms of ground truth data as it tracks over the Bahamas.
Major Hurricane Humberto will not affect the US East Coast but will play a role with steering PTC-9. In addition, Humberto could cause impacts to the island of Bermuda and interest in Bermuda should monitor the progress of Humberto. VoIP Hurricane Net activation for Humberto and impacts to Bermuda are possible this week as well depending on how close Humberto tracks to Bermuda.
Advisories on PTC-9 and Humberto can be seen off the main menu of the voipwx.net web site, via our Facebook and X feeds and via the National Hurricane Center web site at the following link:
The VoIP Hurricane Net will continue to monitor PTC-9, Humberto and any other developments in the Tropics. Thanks to all for their continued support of the VoIP Hurricane Net!
