SATERN Bulletin: Hurricane Irma and Invest 94L

Hurricane Irma:

Hurricane Irma is now about 320 miles east of the Leeward Islands moving west at 14 mph as a Category 4 hurricane with sustained winds of 150 mph and gusts up to 185 mph near the storm’s center.  Some fluctuations in strength are normal but Hurricane Irma is expected to remain a category 4 hurricane. Hurricane Irma is currently about 370 miles wide.

Note: just prior to this posting Hurricane Irma has been upgraded to a category 5 hurricane.

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 Irma by the end of this week.

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 system moves WNW at 10 to 15 mph over the tropical Atlantic Ocean.  Invest 94L has a 90% 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 60% chance of development in the next 5 days.


Tuesday, September 5, 2017:

Because Hurricane Irma is not expected to begin affecting the Leeward Islands until later in the evening on Tuesday, September 5, 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 their location.

Wednesday, September 6 through Saturday, September 9, 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, September 9, 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) between 1100 (CT) / 1600 Z through 1800 (CT) / 2300 Z to be either a Net Control Station or Assistant Net Control Station should contact Net Manager Ken Gilliland (AG6SV) at and Assistant Net Manager Bob Rogers (WA5EEZ) at .

Stations checking-in 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:

a) Is there any hurricane wind damage?  If so, is it minor moderate or severe?

b) Is there any tornado damage?  If so, is it minor moderate or severe?

c) Is there any flood or storm surge damage?  If so, is it minor moderate or severe?

d) Are there any power outages?  If so, how wide-spread?

e) Are there any communications disruptions?  If so, what kind and how wide-spread?

Neither the SATERN Net nor will be accepting Health & Welfare Inquiries (Health & Welfare Messages inquiring about the health and welfare of  people inside an impacted area).  Health & Welfare Inquiries should be referred to the American Red Cross Safe and Well program at: https://safeandwell.

Both the International SATERN SSB Net and the Hurricane Watch Net strongly encourage the participation of bi-lingual (English & Spanish) amateur radio operators on their Nets.

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

International SATERN Digital Net:  There are no current plans to activate this net at this time.


Hurricane Watch Net (HWN):  Net Manager Bobby Graves (KB5HAV) believes that the Hurricane Watch Net will begin operations on Tuesday, 0September 5 2017 at 1300 (CT) / 1800 Z.  Please watch their website at or further details.  SATERN stations should NOT check-in but only monitor the frequency.  Significant situation or damage reports can be sent to National SATERN Liaison Bill Feist (WB8BZH) at . org.

VoIP Hurricane Net:  Net Manager Rob Macedo (KD1CY) reports that the VoIP Hurricane Net will begin operation on Tuesday, 05 September 2017 at 1700 (CT) / 2200 Z and will remain active into sometime on Wednesday, 06 Sepember 2017.  Additional information about activations will be available at

WX4NHC:  The National Hurricane Center amateur radio station will also begin operations on Tuesday, 05 September 2017 at 1700 (CT) / 2200 Z.  They generally monitor the Hurricane Watch Net and VoIP Hurricane Nets.
