Tidal Flooding, Cooler Weather, Tropics Update

August 24th, 2014 at 8:41 pm by under Weather

As the title suggests, there is a lot to talk about in the weather department. Our strong northeast winds will continue tonight and so will the risk of nuisance tidal flooding. Tides will be running higher than normal tonight and tomorrow thanks to the persistent northeast winds and the new moon tomorrow night. If you saw nuisance tidal flooding this morning, you will definitely see it again tonight as water levels should rise even more. Here is the forecast for Sewells Point, which is a benchmark for Southside Hampton Roads and parts of the Peninsula, including Hampton and Newport News.

Water levels will be rising in Yorktown and this could impact parts of York, Gloucester and Mathews Counties tonight. Here is the forecast.

Wind speeds should range from 5-10mph inland and from 10-15mph along the coast overnight. It will be a cool and breezy night with lows in the mid/upper 60s along the coast and lower 60s inland. You may even need the light jacket or sweater early Monday morning.

A ridge of high pressure will build in tomorrow and keep us dry for most of the week. The strong northeast winds will keep us on the cool side once again tomorrow with highs in the upper 70s to around 80°. Average high temperature this time of year is 84°. With the higher than normal tides, there will also be a high risk for rip currents at the beaches and higher surf tomorrow. Wave heights should be between 3-4 feet. Even though we will see perfect beach weather tomorrow, the water will be dangerous to swimmers. Swim near a lifeguard if possible and if caught in a rip current, make sure you swim parallel to the shore until you can swim out of it.

Tropical Update:

Tropical Storm Cristobal is spinning over the Bahamas tonight. Cristobal is expected to slow down as it encounters weak steering currents Monday and Tuesday. This storm is expected to strengthen to a category 1 hurricane by Wednesday as it moves over warmer water and into an area with less wind shear.

The computer models are now in better agreement with the track staying out to sea. If you check yesterday’s blog, you can see the cone of uncertainty was touching North and South Carolina. Now, the cone has been shifted eastward as the models have trended more east with their solutions. I noticed this trend last night.

A trough will move off the East Coast on Wednesday and help keep this storm out to sea. The only impacts that we will see here in Hampton Roads from Cristobal will be higher surf and a high threat for rip currents all week along. Right now it looks like the highest waves will be on Wednesday and Thursday. Stay tuned!
