Team Norfolk Storm Isaias Update 8-2-2020

Posted on August 2, 2020 at 1:24 PM by Daniel Hudson

Team –

We concluded another regional call with the Virginia Department of Emergency Management (VDEM) and the National Weather Service (NWS) based on the National Hurricane Center’s 11am forecast.

As Isaias approaches, there is higher confidence in the inland track being forecasted.  Please note an inland track should serve to limit further strengthening of the system.  Nonetheless, our community is positioned on the right-side which means higher winds.  According to the Maximum Wind Gusts graphic, we can see gusts around 65mph which can result in downed trees / limbs and ultimately power outages.  Additionally, there is also the threat of tornado activity.

Fortunately, most of the rainfall is to occur on the left-side of the storm as shown in the 72-Hour Precipitation Forecast graphic.  Most of the rainfall impacts are expected in the Central Virginia region while we can see upward of a couple of inches; however, this could be heavy at times with the storm’s rain bands resulting in flash-flooding.

At this time there is no serious threat from storm surge; most of the anticipated tidal flooding will occur further into the Bay.

The timing for Isaiah’s visit is expected to be pre-dawn on Tuesday and through the afternoon hours which is displayed in the latest Hourly Graph.

Bottom line, while we may not be inundated with rain and tidal flooding, we will see some significant and impactful winds and in increased threat of tornados.  Given that we “run from the water and hide from the wind”, the likelihood of opening shelters is diminishing though we are still planning for that possibility.  Additionally, particularly should we experience any tornados, we have forestry crews and damage assessment teams on stand-by for when the storm leaves the area in the late afternoon timeframe.

More to come.
