Flood Forecasting System m The Weather Bureau has startedtests of a new electronic detectionsystem that may provide warning of flashfloods to hundreds of river towns. The pilotproject, called AHOS (Automatic HydrologicObservation System), employs 20 remotestations in the Potomac River Valley. Fromfour states, AHOSs sensing equipment trans-mits river and rainfall data continuously toWashington, , furnishing Weather Bureau.
