Temperatures are expected to soar, reaching potentially record-breaking highs. The heat index may climb as high as 112 degrees, with actual temperatures possibly hitting 99 degrees. A high of 100 degrees was set on July 21, 1942, and Tuesday's temperature is just one degree shy of that.

No relief from the heat is expected, as no rain is forecast for the day. Typically, an ocean breeze would provide some cooling, but a west wind is preventing that from happening. Further details about the heat and its impact are available from the source, including the timing and areas affected by the extreme temperatures.
