Restoration of service on a metropolitan power system

A. P. Hayward: Mr. Corney has mentioned the statements concerning the probability of hurricanes and sleet storms occurring in the Pittsburgh area. The weather records do not disclose any hurricanes of the type experienced along the seaboard. The mountains to the east are believed to be a very effective barrier to the full force of any hurricane coming inland and to a certain degree prevent the occurrence of any destructive tornadoes of the type experienced in the Midwest. However, local wind storms of hurricane velocity are not uncommon and, in general, the overhead structures are constructed and adequate clearance provided to withstand these conditions. The sleet hazard is relatively great in this area but for some unforeseen reason there have been no major sleet difficulties on the Duquesne Light system for many years, in spite of severe sleet storms immediately adjacent to the Duquesne Light territory.
