Space weather seeks to understand and forecast the magnetic phenomena on the sun and in the heliosphere that affect the earth. Since the origin of the solar and heliospheric magnetic field lies inside the sun, helioseismology can play a significant role in space weather. However, the use of helioseismic observations for space weather is just now starting. In this presentation, we summarize the current research that is being done in this area. The main areas under development are the use of far-side mapping to detect and characterize active regions before they rotate onto the earth-facing side; the measurement of subsurface vorticity and surface magnetic field to identify active regions that could potentially produce significant flares; and the monitoring of temporal variations of subsurface vorticity to forecast the occurrence of large flares.
