NWS Boston/Norton Winter Weather Advisory Statement:

The second part of this message is a special announcement – Boston Marathon Weather Coordination Message as issued in prior years:

While this may be a bit off topic for some SKYWARN Spotters, Amateur Radio Operators and Red Cross volunteers, many of which are SKYWARN Spotters, will be involved in the Boston Marathon on Monday April 16th. To reach out to the highest level of Amateur Radio Operators involved in the event, this coordination message is being sent out to the SKYWARN email list and posted to the various Amateur Radio lists. We appreciate everyone’s patience with this message. This is a joint message between the Amateur Radio Emergency Services (ARES)-SKYWARN program at NWS Boston/Norton and Eastern Massachusetts ARES. Due to the storm conditions and the fact some level of SKYWARN Activation will occur, messages will occur through at least Sunday Evening on the storm event.

Eastern Massachusetts ARES members not participating in the Boston Marathon are requested to be on standby for marathon activities on Monday April 16th from 6 AM-7 PM for any significant issues outside of the Boston Marathon that may require Amateur Radio Emergency Communications support and for any unexpected issues on the Boston Marathon route. With over 280 Amateur Radio Operators staffing the Boston Marathon route, the start line and the finish line, if an issue arises needing Amateur Radio support outside of the Marathon route or an unexpected issue arises in marathon operations, it is important that any ARES members not involved in the marathon can help with any response that is required. The Amateur Radio Station at the National Weather Service in Boston/Norton, WX1BOX, will be active on Monday April 16th for the Boston Marathon to provide weather support to the Amateur Radio community participating in the marathon and to gather any weather reports of significance during the marathon. This station will also be used to coordinate any ARES response to any significant incidents regarding Amateur Radio support outside of the marathon zone including any incidents that need to be provided to the State EOC for situational awareness information.

The Massachusetts Emergency Management Agency (MEMA) Multi-Agency Coordination Center (MACC) at the SEOC (State Emergency Operations Center) will be active for the Boston Marathon. Amateur Radio Operators will be at the SEOC to support Amateur Radio communications and will be on the air under call sign, WC1MA, while many agencies will be there performing primary operations for the marathon.

The weather outlook is definitely less than ideal for volunteers and is also not ideal for runners though not as significant as a warm weather event would be for the runners. Rain will be widespread across the marathon route in the morning hours and the heaviest rain is expected in the late morning through early evening. This may result some poor and drainage street flooding in the region. Strong winds are also possible with wind gusts in the 30-45 MPH range in the interior with the highest gusts as you get closer to the Metro Boston areas. Areas of Southeast New England will have wind gusts to 45-50 MPH and this may result in Wind Advisories as we get closer to the event. This could result in isolated pockets of tree and wire damage and isolated power outages. An isolated thunderstorm or two with attendant lightning risk is also possible but exact locations and whether they would occur on the marathon route are difficult to determine. All runners, volunteers and spectators should monitor future weather forecasts and should prepare accordingly for these conditions. SKYWARN Activation with Ops at NWS Boston/Norton will commence at 600 AM Monday for the storm on Marathon Monday lasting through 600 PM Monday Evening.

From a SKYWARN perspective, the 146.64-Waltham Repeater and 145.23-Boston Repeater are being utilized for Marathon operations. From an ARES perspective, the Minutemen Repeater Association Repeater Network is being utilized for marathon operations. Please review the SKYWARN Frequency listing for your closest alternate repeater from a SKYWARN or ARES perspective.

For Amateur Radio, Red Cross and all other volunteers along the route, it is recommended that you dress in layers for this event so that you can put on or take off clothes as needed for comfort. Rain gear is a must either with a clear poncho or a rain coat where you can still display appropriate credentials outside of the raincoat. Be sure to drink liquids and eat properly during the event and that you are self-sufficient so that you can be of full help to the function and not distract everyone from the main purpose of supporting the runners by having a health issue on your end that can be avoided. For volunteers, the BAA has sent around via email weather safety tips and suggestions on clothing and other safety tips.

For those people that are planning to go to the Boston Marathon as spectators, the following link details guidelines for spectators for the 2018 Boston Marathon:

Another coordination message will be posted by 1100 PM Sunday Evening. We appreciate everyone’s support in this event and hope those that volunteer enjoy themselves and feel the self-satisfaction of supporting this historic event and those that are monitoring the Marathon or events outside of the Marathon realize that the monitoring is an important function as well and is a testament to being able to scale other incidents beyond the marathon if required. Thanks to all for their support!
