Hello to all..

The VoIP Hurricane Net and WX4NHC are securing Operations at 630 PM EDT/2230 UTC. While Isaac is becoming better organized, it remains a tropical storm and is passing through the Florida Keys. The new track guidance brings most of Isaac’s effects out over the open Gulf of Mexico for Monday with the exception of some minimal tropical storm effects along the immediate west coast of Florida. Latest model guidance and NHC track guidance brings Isaac to the northern Gulf Coast between Louisiana and Florida Tuesday into Wednesday when the next VoIP Hurricane Net and WX4NHC activation is likely to occur.

We appreciate everyone’s support monitoring Isaac today as it passed through the Florida Keys. Thanks to all for their continued support of the VoIP Hurricane Net!

Hello to all..

The Atlantic Tropics are in another active period with Tropical Storm Helene, which regenerated from the remnants of Tropical Depression 7, soon to make landall in Mexico, Hurricane Gordon which will impact the Central and Eastern Azores Islands of Portugal with tropical storm conditions and an area of disturbed weather organizing west-southwest of the Cape Verde Islands. Here are the latest updates:

Hurricane Gordon is a Category-1 hurricane on the saffir-simpson hurricane scale with 80 MPH winds located 760 miles west-southwest of the Azores. Gordon is moving East at 18 MPH with a turn toward the east-northeast expected Sunday and Gordon is expected to approach the Central and Eastern Azores islands with tropical storm force conditions and a Tropical Storm Warning is in effect for the Central and Eastern Azores Islands. Gordon should maintain hurricane strength but weaken to a tropical storm on Sunday as it approaches the Azores.

Tropical Storm Helene formed from the remnants of Tropical Depression 7 and is expected to make landfall later today. A Tropical Storm Warning is in effect for the coast of Mexico from Barra De Nautla to La Cruz. The biggest threat from Helene is heavy rainfall.

A tropical wave located a couple hundred miles west-southwest of the Cape Verde Islands continues to produce showers and thunderstorms and environmental conditions appear conducive for gradual development. This system has a medium chance, 40% of becoming a tropical cyclone during the next 48 hours as it moves westward at 15-20 MPH.

Hello to all..

The following is the Updated Atlantic Hurricane Season Forecast and an update on the Atlantic Tropics. The Atlantic Tropics remain active for this time of year.

The NOAA Atlantic Hurricane Outlook and Dr. Gray’s Atlantic Hurricane Season Forecast updates for August have been issued. The NOAA outlook keeps a near normal season forecast, however, they have also raised the percent probability of an above normal season to 35% which means a near to slightly above normal season is now expected. Dr. Gray’s seasonal forecast revised the total named storms upward to 14 stating a near normal season remains forecasted and below normal compared to the last 2 years. The forecast outlooks from Dr. Gray and NOAA are listed below:

Turning our attention to the Atlantic Tropics in the short term, Tropical Storm Ernesto made landfall in Southeast Mexico as a tropical storm. The main threat from Ernesto for Southeast Mexico is heavy rainfall.

Hello to all..

Tropical Storm Ernesto will be making landfall later this morning along the Southern coast of the Bay of Campeche. Ernesto is currently a strong Tropical Storm with maximum sustained winds of 70 MPH. Ernesto could briefly reattain hurricane strength before landfall but its close proximity to the coast, the fact that it is not a hurricane currently and the rural portion of Mexico that it will affect will preclude a formal net activation. The VoIP Hurricane Net Management Team will continue to monitor the progress of Ernesto during the day today. Ernesto will weaken as it tracks over land later this afternoon and tonight. Ernesto Advisory information can be seen off the Main Menu of the Web site and can be seen via the National Hurricane Center web site via the following link:

http://www.nhc.noaa.gov

A low pressure area 1050 miles west of the Southern Cape Verde Islands has a high chance 70% of development into a tropical depression as it moves westward at 15 MPH. The VoIP Hurricane Net Management team will continue to monitor the progress of this system.

The remnants of Florence are located several hundred miles northeast of the Leeward Islands and producing disorganized shower and thunderstorm activity. Redevelopment of this system is not expected at this time.

The VoIP Hurricane Net Management Team will continue to closely monitor the Atlantic Tropics. Thanks to all for their continued support of the VoIP Hurricane Net!

Hello to all..

The VoIP Hurricane Net and WX4NHC, the Amateur Radio Station at the National Hurricane Center, secured operations for Hurricane Ernesto at 1 AM ET Wednesday Morning. Ernesto has weakened into a tropical storm but may prompt an additional activation on Thursday Afternoon and Evening if Ernesto regains enough intensity and reaches hurricane strength as it moves out over the extreme Southern Gulf of Mexico potentially making landfall near Veracruz Mexico late Thursday Afternoon/Evening. Ernesto Advisory information can be seen off the Main Menu of the Web site and can be seen via the National Hurricane Center web site via the following link:

http://www.nhc.noaa.gov

The VoIP Hurricane Net would like to thank NP3OD-Fransisco and 9Z4FZ-Julien and several other Amateur Operators on Trinidad for their significant efforts in providing relays into the affected area. Francisco-NP3OD was able to speak Spanish to several Amateur Operators on the XE3RA-L system and the Hams in Trinidad were able to establish contact to the Mexican HF Net on 40 Meters. This was very helpful in acquiring some information from the area. We also like to thank the Mexican Hams that provided what information they could provide to NHC forecasters and WX4NHC.

We also want to thank N0UAM-Jim Sellars, Assistant Director of Operations for the VoIP Hurricane Net, who discovered a weather station in Costa Maya at the Margarita del Sol Costa Maya Resort which was right in the path of Ernesto. Many reports from that station were relayed until the connection to the weather station was lost due to a power outage. An attempt was made to contact someone there on site but their cell phone had a ‘temporary out of service’ message so no further data could be gathered from this station.

Hello to all..

Tropical Depression (TD)5 has become Tropical Storm Ernesto, the fifth tropical system of the 2012 Atlantic Hurricane Season, about 295 miles East of the Windward Islands with Maximum Sustained Winds of 50 MPH and a minimum central pressure of 1006 Millibars or 29.71 Inches. Ernesto could strengthen slightly as it passes through the Windward Islands but is expected to stay below hurricane strength as it passes through the Windward islands. Ernesto may reach hurricane strength in 4 to 5 days over the Caribbean Sea. At this time, VoIP Hurricane Net activation is not expected over the next few days but we will continue to monitor the progress of Ernesto.

Advisory information on Ernesto can be seen off the Main Menu of the voipwx.net web site. The advisory information can also be seen via the National Hurricane Center (NHC) web site via the following link:
