 Figure 2. Graph of rainfall at Pensacola, Fla., and Brewton, Ala., showing monthly
 averages, maximums and minimums, and yearly rainfall for the period 1926-61.


 The pattern of seasonal distribution is the same over the entire area,
the wettest periods occurring in early spring and late summer and the
driest in October and November. Except during October and November,
an average rainfall of at least 4 inches each month can be expected.
October and November have an average rainfall of about 2.9 inches and
3.8 inches, respectively. An average rainfall of over 6.0 inches occurs dur-
ing March, July, August, and September. July has the highest average,
with 7.4 inches. There is always the possibility, however, of having a dry
month during normally wet seasons or a wet month during seasons
which are usually dry. For example rainfall in October has varied from
near zero to a maximum of 20.5 inches at Pensacola, and March,
normally a wet month, has experienced as little as 0.9 inch of rainfall.
 Another interesting aspect of the rainfall of the area is the high
intensity-as much as 0.6 inch has been measured during a 5-minute
period. Rainfalls of 3.5 inches during a 1-hour period and daily rainfalls
in excess of 6.0 inches are not uncommon.
