A large oak tree came crashing down Wednesday morning along American River Drive, blocking the street and hitting the roof of a house.
The tree split down the middle after several days of hot weather. Work crews worked through the morning to clear thick branches from the roadway at American River Drive and Callnon Court near Watt Avenue.
What caused the tree to fall is not clear. The tree, however, came down after several days of hot weather. During hot days, tree limbs and trunks are susceptible to a phenomenon called "summer branch drop." Summer branch drop mainly affects older trees.
Some arborists explain it this way: During a hot stretch, water is sent up a tree to cool its limbs. The branches become too heavy with water and break.
Wednesday's high temperature in downtown Sacramento was 105 degrees, according to the National Weather Service. A high of 102 is forecast today, with the temperature Friday expected to top out at 97. The normal high for this time of year is 94 degrees.
