Gaston Video

Remembering Gaston

It was five years ago today when Tropical Storm Gaston moved through our area.

This storm dumped as much as 12" of rain in some locations across metro Richmond.

Flash flooding took the lives of eight people - five of which were motorist who tried to drive through flooded roadways. In addition, Gaston spawned twelve F0 tornadoes. The total damage estimate for the whole storm was roughly $30 million. You can find additional information at the following link:

Big Changes Headed This Way




The coolest air mass we have seen since Summer began will be moving into the Mid-Atlantic on Monday. The high temperature map from today is posted above, and gives a glimpse of what is to come. Highs across the Great Lakes were in the 50s and 60s today, while the desert southwest had temperatures nearing 120 degrees. This large spread in temperatures is due to a meridional (north-south) upper-level flow, indicated by the top graphic (forecast for Sunday night). Hot tempertures are found under the ridge (SW US) and cool temperatures are found under the trough (Great Lakes). The strong trough will dig into the eastern US, bringing highs in the upper 60s and low to mid 70s to central Virginia on Monday and Tuesday.
