Hello to all…

Hurricane Idelma will cause direct impacts to Bermuda as we get into late Wednesday Afternoon through Thursday Morning. A Hurricane Watch is posted for Bermuda and it is expected that the watch will be converted to a Hurricane Warning later today. VoIP Hurricane Net Activation is likely for Idelma and impacts to Bermuda in the Wednesday Afternoon to Thursday Morning timeframe. A net activation announcement will be posted later tonight or Wednesday Morning. Presuming net activation occurs for Bermuda as expected, we will cancel the VoIP Hurricane Prep Net for Saturday Evening due to the net activation for Idelma. Hurricane Humberto will pass west and north of Bermuda and may cause wind gusts to tropical storm force today over Bermuda.

Advisories on Imelda 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:

Hello to all…

Some fairly significant changes to the forecast for Tropical Storm Imelda and Major Hurricane Humberto could bring tropical storm conditions to Bermuda. Here are the latest updates:

Tropical Depression (TD) 9 became Tropical Storm Imelda earlier this afternoon and a Tropical Storm Warning remains in effect for the Bahamas. Our net has forwarded a couple reports of tropical storm force conditions in the Bahamas that was used in the 5 PM EDT advisory on Imelda. Rain Gauge totals in the area range from about 2-5.5″. Imelda will continue to intensify and likely reach hurricane strength late Monday Night or Tuesday.

The track of Imelda now keeps it far enough offshore where the Southeast US coast will get some heavy rain and potential flooding between Imelda and interaction with a frontal system but the core of the strong winds will remain offshore of the Southeast US coast. The NHC track also now has it hooking right well away from the Southeast US coast. Therefore, VoIP Hurricane Net activation is not expected over the next 3-4 days and local SKYWARN groups will handle heavy rainfall and flood threat, however, some model solutions bring Imelda close to Bermuda and this will be monitored as we get towards late this week for possible net activation. We will also provide any known reports of tropical storm force conditions from the Bahamas and if needed, other areas, to WX4NHC, the Amateur Radio Station at the National Hurricane Center, via our reporting form.

Major Hurricane Humberto is a significant reason for why Imelda’s track has changed and is now a more offshore solution. Humberto’s hurricane core is currently expected to stay away from Bermuda at this time but tropical storm conditions could affect the island in the next couple days and a Tropical Storm Watch is posted for Bermuda. We will continue to monitor Humberto’s progress until he is past Bermuda.

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.

Hello to all…

The Atlantic Tropics have become more active this week. Here are the latest updates as of Wednesday 9/24/25 – 800 PM EDT Update:

Hurricane Gabrielle is a threat to the Azores Islands of Portugal with hurricane force conditions expected Thursday Night to Friday Morning and Hurricane Warnings are in effect for the Azores. We have had stations from time to time from that area on the net and we will likely do a “limited” net activation for Gabrielle and her impacts on the islands. Please contact the net management team if you have any contacts in the Azores that could assist with reporting storm conditions as Gabrielle passes through the islands.

Tropical Storm Humberto has formed in the Atlantic. Humberto is expected to intensify into a hurricane in the next few days while remaining in the open waters of the Atlantic. Thereafter, its unclear whether Humberto remains out at sea, impacts Bermuda or the US East Coast due to interaction with another tropical wave in the Eastern Caribbean Sea that is expected to emerge over the Bahamas.

Advisories on Gabrielle and Humberto can be seen on the voipwx.net web site under Atlantic Tropical Products, via the voipwxnet Facebook/X feeds or via the National Hurricane Center web site at the following link:

https://www.nhc.noaa.gov/

The area of disturbed weather as mentioned above in the Eastern Caribbean Sea (designated as AL94) has a medium chance 40% for development in the next 48 hours and a high chance, 80%, for development over 7 days. The system is expected to be classified and if it reaches tropical storm strength as expected, it would be named Imelda. This system could have a closer track to the US East Coast but it is very low confidence due to its likely interaction with Humberto and whether that interaction leads to the “Fujiwhara Effect” occurring or simply has the track influenced being near Humberto. Information on the “Fujiwhara Effect” can be seen at the following link:
