From the National Weather Service:
Wet weather is ahead for much of the week.
After a pleasant spring day Monday, we'll be monitoring the potential for river and stream flooding from two different storm systems.
First for Monday, high pressure will be in control of our weather with bright sunshine and highs well into the 50s, if not around 60 in some interior locations. The exception will be near the coast, where sea breezes will keep temperatures in the 40s.
The first storm system will bring rain Monday night and Tuesday, which could be heavy. Right now we are forecasting rainfall totals of 1.0 to 1.5 inches across much of the region. This should not be enough to cause flooding on rivers and streams, since we would need closer to 2 inches for that, but at the very least expect minor flooding of streets and low lying areas such as underpasses.
The second storm will bring more rain Thursday. Although it's a few days away, it has the potential to bring another 1.0 to 1.5 inches of rain, which could result in flooding, especially after the first storm.
The bottom line is to pay attention to the latest forecasts this week, especially if you live or work in an area which is prone to flooding.
