Boston Marathon Weather and Storm Coordination Message #2 – Monday April 20th, 2015

Hello to all..

..A storm system is on track to bring rain, heavy at times, cool, damp, and some windy conditions below Wind Advisory levels during the timeframe of the Boston Marathon. After the marathon, rain and some windy conditions below Wind Advisory levels will continue with the possibility of minor coastal flooding at the time of the Monday Evening and overnight high tide cycle and the possibility of isolated thunderstorms. The cooler conditions on Monday despite the rain may be ideal for runners but not as ideal for volunteers and spectators. Volunteers and spectators along the route should dress accordingly given the current weather forecast..
..WX1BOX, the Amateur Radio Station at NWS Taunton, will activate at 600 AM to monitor weather conditions for the Boston Marathon and surrounding areas during this storm. Most conditions should stay below SKYWARN Reporting criteria but monitoring of weather conditions will occur throughout the day supporting the event and in case any conditions reach SKYWARN reporting thresholds..
..A Coastal Flood Advisory is now in effect from 8 PM-12 AM Monday Evening for southeast coastal Rhode Island and Southern Bristol and Southern Plymouth Counties of Massachusetts. A Coastal Flood Advisory is now in effect from 12 AM Monday Evening through 4 AM Tuesday Morning. This is for minor coastal flooding at the time of high tide Monday Evening and during the overnight hours Monday Night into early Tuesday Morning..
..Eastern Massachusetts ARES has been mobilized for those ARES Amateurs not directly involved in the Boston Marathon for any incidents unrelated to activities in the Boston Marathon zone that need support..

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 20th. We appreciate everyone’s patience with this message although for this year, there is a storm system that will affect the region Monday Morning through Monday Evening. The storm is expected to be below most SKYWARN reporting thresholds but could make for poor conditions for those outside for extended periods of time particularly for those who do not prepare for the conditions in advance. The storm conditions are also close enough to SKYWARN reporting criteria to warrant a coordination message.

The weather outlook for the Boston Marathon has a coastal storm system moving into the area. This will result in overcast skies with rain starting in the early to mid-morning. Rain will start between 7-10 AM in Western Massachusetts and Northern Connecticut and reach Eastern Massachusetts and Rhode Island between 10 AM-1 PM. Rain will start off light and then become heavy at times between Noon-2 PM in Western Massachusetts and Northern Connecticut and between 2-5 PM in Eastern Massachusetts and Rhode Island including the marathon route. There will be some windy conditions as well with the rain. Winds will be out of the East at 15-20 MPH with gusts to 30 MPH possible and around 35 MPH at the coast line. These winds are unlikely to cause any significant damage but it will add to the cool, raw feel to the day for volunteers and spectators. Total rainfall by Monday Evening near the end of the marathon is likely to be around 0.50-1″ of rain across the region. The rain will continue after the marathon is completed into Tuesday with total rainfall by the end of the event Tuesday Evening in the 1-2″ range with isolated higher amounts possible especially in southeast New England. Any thunderstorm activity at this time, looks to be after the marathon is completed but this will be monitored. Temperatures will be in the 40s to around 50 degrees. The wind will make conditions feel cooler with wind chills in the mid-30’s to lower 40’s.

After the marathon is completed, along coastal areas, minor coastal flooding is likely at the time of high tide Monday Evening and overnight across the Massachusetts and Rhode Island coast lines. A Coastal Flood Advisory is now in effect from 8 PM-12 AM Monday Evening for southeast coastal Rhode Island and Southern Bristol and Southern Plymouth Counties of Massachusetts. A Coastal Flood Advisory is now in effect from 12 AM Monday Evening through 4 AM Tuesday Morning. Below is the NWS Taunton Coastal Flood Advisory Statement, Hazardous Weather Outlook and Area Forecast Discussion with details on the upcoming storm for Marathon Monday:

It is noted that the 146.64-Waltham and 145.23-Boston Repeater are being used for Marathon operations. There will be no SKYWARN Nets on these frequencies. Other frequencies will be utilized as required and can be seen at the following link:

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. 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. Rain gear will be very important for this year’s marathon for volunteers and spectators. Runners will need to keep the conditions in mind accordingly as well. As you are constructing any medical tents along the route, while winds are not expected to be damaging in nature, the winds may be enough to effect any tents that are not tied down properly. Assured that they are tied down and staked properly to avoid any issues.

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

At the request of Eastern Massachusetts ARES Section Emergency Coordinator, Mike Neilsen-W1MPN, ARES Amateurs not directly involved in the Boston Marathon has been mobilized for any issues outside of the marathon zone. See the following link for further details:

This will likely be the last coordination message on Boston Marathon weather. An additional shortened coordination message could be posted late Monday Afternoon/early Monday Evening regarding any storm related issues overnight Monday including the minor coastal flood potential. 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 conditions for this year’s Marathon understand that this is an important function as well for situational awareness purposes. Thanks to all for their support!
