Hurricane Irma:

Hurricane Irma is now about 490 miles east of the Leeward Islands moving west at 13 mph as a low–end category 4 hurricane with sustained winds of 130 mph. The storm is expected to strengthen over the next 24 hours. Hurricane Irma is currently about 360 miles wide.

Hurricane Irma is a growing threat to the United States, but will first pose a danger this week from the Leeward Islands and Puerto Rico and potentially to Hispaniola, the Bahamas and Cuba. By next weekend, Irma will begin to turn north in the direction of a departing southward dip in the jet stream that will set up in the Eastern United States. Where that northward turn occurs will be critical for what impacts parts of the United States may see from Irma. It is far too soon to speculate on the specifics surrounding any potential U.S. threat from Irma, but it could pose a big danger as it draws closer later this week. The U.S. is likely to be impacted by Irmai by the end of this week. The latest “Cone of Error” map and “Sphaghetti Models” (computer generated potential tracks) are attached below:

 

Invest 94L:

Invest 94L is an elongated area of low pressure located several hundred miles southwest of the Cabo Verde Islands. It continues to produce disorganized showers and thunderstorms. Environmental conditions are expected to be conducive for gradual development and a tropical depression is likely to form later this week as the sytem moves WNW at 10 to 15 mph over the tropical Atlantic Ocean. Invest 94L has an 80% chance of becoming a tropical system within the next 5 days. If this becomes a named storm, it will be called Jose.

There is also a second disturbance (Disturbance #2) in the Bay of Campeche. It is a trough of low pressure. Environmental conditions are marginally conducive for some slow development of this system with the National Hurricane Center giving it a 50% chance of development in the next 5 days.

Tuesday, 05 September 2017:

Because Hurricane Irma is not expected to begin affecting the Leeward Islands until later in the evening on Tuesday, 05 September 2017, SATERN operators are encouraged to begin monitoring either of the two Hurricane Watch Net frequencies on 14.325 MHz or 7.268 MHz, depending upon propagation for each station.

Wednesday, 06 September through Saturday, 09 September 2017:
Beginning Wednesday, 06 September 2017, the International SATERN SSB Net will move to a Delta II (extended monitoring) status from 0900 (CT) / 1400 Z until 1800 (CT) / 2300 Z. From 1800 (CT) / 2300 Z until 0900 (CT) / 1400 Z the next day, SATERN operators will again be encouraged to monitor either of the Hurricane Watch Net frequencies as conditions dictate.

This same schedule will continue through at least Saturday, 09 September 2017. It is possible that this same schedule will be continued into the next week depending upon (a) the level of threat posed by Hurricane Irma, and (b) the needs of The Salvation Army.

Stations interested in signing up for a one or more one hour slot(s) from 1100 (CT) / 1600 Z until 1800 (CT) / 2300 Z to be either a Net Control Station or Assistant Net Control Station should contact Net Manager Ken Gilliland (AG6SV) at ag6sv@att.net and Assistant Net Manager Bob Rogers (WA5EEZ) at BobRgrs@hotmail.com.

Reporting stations will be asked to provide the Net Control Station with the following information:

  1. Any emergency, priority or health & welfare messages that may come out of the impacted area(s)
  2. A brief situation report from the stations' location that includes:
    1. Is there any hurricane wind damage? If so, is it minor moderate or severe?
    2. Is there any tornado damage? If so, is it minor moderate or severe?
    3. Is there any flood damage? If so, is it minor moderate or severe?
    4. Are there any power outages? If so, how wide-spread?
    5. Are there any communications disruptions? If so, what kind and how wide-spread?

Hurricane Irma is a particularly dangerous storm which will bring category 4 winds and torrential rain to numerous Caribbean islands and very possibly somewhere in the U.S. mainland afterwards.

International SATERN Digital Net:

There are no current plans to activate this net.
