南加州本周五开始经历一场秋季晚期热浪。1国家气象局预警气温将比正常值高15-20度，持续至少一周。1洛杉矶市区气温接近100华氏度，内陆地区预计可能超过100度。1
气象专家指出这次热浪具有历史罕见性。10月2日的极端高温比有记录以来最热的10月2日高出近7华氏度，比75华氏度的历史平均值高约30度。1国家气象局气象学家理查德·班恩表示："我们预期气温将比正常值高15-20度——这相当显著"。1UCLA地理与城市规划教授凯利·特纳指出："周五的极端高温是罕见的"。1
气候变化正在加剧这类极端天气事件的强度。UCLA大气物理学家大卫·尼林表示："气候变暖无法逃避地增加了热浪的强度"。1热浪期间，洛杉矶道奇队将在国家联盟分区赛中对阵亚特兰大勇士队。1
Southern California is experiencing an unseasonable heatwave beginning Friday, with the National Weather Service warning that elevated temperatures will persist for at least a week.1 Los Angeles city proper is expected to see temperatures approaching 100 degrees Fahrenheit, while inland areas could exceed that threshold significantly.1 Forecasters predict temperatures will run 15 to 20 degrees above normal values.1
The extreme heat being recorded this week is historically anomalous.1 October 2nd's peak temperature exceeded the previous record for that date by nearly 7 degrees Fahrenheit and stands approximately 30 degrees above the historical average of 75 degrees.1 National Weather Service meteorologist Richard Bane stated: "We expect temperatures to be 15 to 20 degrees above normal—that's quite significant."1 According to experts, climate warming is intensifying the severity of such heat events. UCLA atmospheric physicist David Neilin noted: "Climate warming inevitably increases the intensity of heatwaves."1 UCLA geography and urban planning professor V. Kelly Turner characterized Friday's extreme conditions as "rare."1
The heatwave arrives during a significant sporting event, as the Los Angeles Dodgers will face the Atlanta Braves in a National League Division Series during this period.1
