Rain Storm and Subsequent Flooding Experienced by Ontario County on July 28th, 2014
Many Western New York residents awoke to a rather startling emergency alert on their phones/mobiledevices in the wee hours of the morning on Monday, July 28th. While residents took to social media
to share their displeasure regarding their abrupt awakening, the National Weather Service had issued
a severe weather warning which would prove crucial as the day went on.
Meteorological Aspects (For Those who are Interested)

The meteorological ingredients were in place to facilitate a heavy rain event. A strong low pressure
system had moved into the region over night (left image). This low pressure system coincided with
an area of strong positive vorticity. Vorticity is a measure of the localized rotation of air. The advection
of vorticity at high levels in the atmosphere will result in a response at the surface which will attempt to
offset the effects of the advection. In layman's terms, the lower the pressure at the surface, the higher (more positive) the vorticity in the upper levels of the atmosphere. Vorticity is best viewed at the 500 millibar (mb) level. The image to the right indicates the positive vorticity (deeper yellows and orange) over our region during this event. Positive vorticity usually involves stronger winds and unstable conditions, which were present on this day.

Local News and Reaction After the Storm
The Town of Richmond was one of the more significantly affected areas. One resident had just secured a building permit to construct a new insurance office. According to this resident, "The creek has been an issue for 10 or 15 years. It used to flood every 10 years or so and this year, it's flooded twice already. We are hoping we would get through the building process before the next flood and obviously it didn't work so well." (full article). These sentiments were felt by many residents as this was the second major rain event of the summer. In parts of Richmond, 5 inches of rain had already fallen by 11:00am. |
