J Cecil Alter government meteorologist as he studied weather m maps ps disclosing the cause of the blow Barometric conditions at the time were perfect for or creation of a high velocity wind but It Is unlike unlike- ely e- e ly y such an exact sit situation will occur again oftener than once in 25 to 40 years Mr Alter said The wind reached a maximum ve- ve of 44 H miles per hour at p. p i. i in m. m Thursday and nearly 12 ho hours rs later ater was blowing 39 miles per hour hourat at 40 a. a m m.
