Smoky air from the Great Dismal Swamp Fire returns

Many of you in central Virginia will smell the smoke from the Great Dismal Swamp fire again Wednesday because of a wind shift overnight from the Southwest, transporting the smoky air into our region (as it has done so already several times this month). The fire started August 4th as a result of a lightning strike in the Refuge. Since then, southerly winds at times have allowed the smoky air and smell to spread as far north as the DC and Baltimore metro areas. Today, we will smell the smoke again with a persistent southerly wind. Here's the latest update from the Active Fire Mapping Program:

Tuesday Morning Update on Irene

Here's the Tuesday morning visible satellite image of Category Two Hurricane Irene with maximum sustained winds of 100 mph, as viewed from space:

Hurricane Irene did not strengthen overnight, but is becoming better organized as it moves away from the Dominican Republic and Haiti.

Irene's track through the Bahamas looks likely based on good consistency between forecast models.

Sea surface temperatures are very warm and highly favorable for intensification of Irene as it passes into and over the Bahamas. By Wednesday, Irene should have strengthened into a "major" hurricane at Category Three strength of winds at least 111 mph or stronger. While continuing to pass over these warm waters east of Florida, this intensity should be maintained.

An upper-level wave from the U.S. should encourage Irene to take a more northerly shift late Saturday into early Sunday, aiming Irene for the southern North Carolina coast:

It is crucial as we look into this weekend to not pay as close attention to the little red hurricane icon on the map, but rather to the white highlighted area of potential impact in our region:

Speaking of the "area of impact," here are some of the possible weather impacts we may experience in central Virginia:

Here is the model spread for our region of the Mid-Atlantic Coast (the lines represent the various forecast centers of the storm's track):

Irene should continue as an extremely strong cyclone as it transitions to an extra-tropical system in New England Sunday-Monday next week:

Update on Hurricane Irene

Hurricane Irene is now a category 2 storm with maximum sustained winds of 95 mph, and a minimum central pressure of 981 mb. The image above shows the spaghetti plot for all tropical models handling the track of Irene this evening. There is now almost full consensus that Florida will be spared, with a landfall near the SC/NC border more of a likelihood. Extrapolation of the curved path will take the storm across eastern and parts of central VA. If the trough moving through the eastern U.S. is fast and strong enough, there is a chance Irene could only graze the OBX, and miss VA. As for now, prepare for some adverse weather in central and eastern VA this weekend. ZD
