Steady rain fell for much of the night around San Diego County and showers are expected to continue into Thanksgiving Day. As of 4:00 AM at the official reporting station at Lindbergh Field, 1.00" has fallen which is well above normal for this date. Rainfall amounts vary greatly around the county, from a couple of tenths of an inch to more than an inch and a quarter.
As colder air moves into the county tonight, it should keep showers going through at least midday tomorrow and could even kick off some thunderstorm activity. As a result, and because some showers will be quite heavy at times, a flash flood watch remains in effect through tonight.
In addition, today is one of the busiest travel days of the year and you should expect delays, not only at the airports but on all the county's major freeways as well. There have already been road closures and flooded streets and, by 4:00 AM there were already as many accidents working as there are over an entire normal day.
Closures and other highway problems are subject to change depending on current weather conditions. Check this sight regularly throughout the day for continuous updates.
