Since yesterday evening’s update, we witnessed the
significant difference between the terms forecast and observation.
Forecasts are made based on imperfect data and ever-changing conditions.
Observations are just that – conditions which are actually seen. As
stated by Tom Knutson of NOAA/Geophysical
Fluid Dynamics Laboratory and Robert Tuleya of ODU’s Center for Coastal Physical Oceanography:
“If we had observations of the future, we obviously would trust them more than
models, but unfortunately… observations of the future are not available at this
time.” In other words, forecasts are always subject to change!
Last night far exceed the half inch of rain forecasted in
the hourly graph. Fortunately the infrastructure has been doing well
receiving and moving that water and with the exception of the usual trouble areas
(i.e. 4th View), there have been no reports of significant flooding
on the roadways. This includes the Tidewater underpass just south of
Lindenwood Ave which had been temporarily closed yesterday due to an electrical
issue with one of the pumps. Pump crew responded quickly and corrected
the issue. We currently stand at an around a 40-50% percent chance of
rain throughout the day with a fraction of an inch expected. Furthermore,
the expected high tide at 2:30pm this afternoon is 4.1’ – short of the Minor
flood stage of 4.5’ but may still cause pockets of flooding on some of the
usual trouble spots. All conditions normal today and the evening commute
should not be impacted.
Unless conditions change (again…), this should be the last
update related to this weather system.
This update will also be sent to ALLEXCHANGE and our Team
Norfolk partners.
Thank you and have a great day!
Jim
