Boston Marathon adjusts for inclement weather

BOSTON -- The Boston Marathon has announced several adjustments for the world's oldest annual marathon because of the stormy forecast.

Organizers of the 123rd race are preparing for rain and strong winds on Monday. At one point, the forecast called for morning temperatures in the 30s, with the potential for wind chills in the low 30s, but that has changed significantly. The morning temperatures are now predicted to be in the 50s, with the potential for temperatures rising to the 60s in the afternoon.

According to a press release from the Boston Athletic Association: "The weather in New England can change significantly from day to day. The forecast has changed throughout this week and may continue to."

To be safe, there will be additional medical vehicles to pick up athletes who can't complete the course. Tent walls and heat will be added at the staging areas, and more ponchos will be available. Volunteers will receive hand warmers.

Organizers also eliminated a 25-minute gap in the start times for two waves of runners.

If the forecast holds, it will be the second year in a row that the race has been plagued by rainy, windy and generally miserable conditions.
