DISCUSSION: If you live in the Mid-Atlantic portion of the United States (centered on the Washington DC area), be prepared for a heavy rain (and possible flooding) event, even though it has been dry for the past month. Moisture coming from all over the place at different levels of the atmosphere and you can take note with this moisture analysis from different polar and geostationary satellites.

DISCUSSION: As a strengthening Hurricane Hermine continues to makes its final approach into Northern Florida (and specifically with the most significant impacts likely expected to be felt across the span of the Panhandle), there will remain a much larger threat for widespread flooding over the next few days. This increased flooding threat will be a direct consequence of Hurricane Hermine weakening coupled with a persistent flow of tropical moisture with a northeasterly trajectory along the East Coast of the United States. This northward-moving moisture-laden air will generate an increased potential for longer-duration periods of heavy rainfall anywhere from Northern Florida to the Mid-Atlantic region due to the weakening tropical storm's slow rate of northward movement over the next few days. Bearing that in mind, it is imperative to quickly organize your preparation plans for this tropical storm immediately in order to be prepared well ahead of its arrival. Timing it out, the center of a much weaker Tropical Storm (or possibly Tropical Depression) Hermine should be located just offshore from the South Carolina coastline by early Saturday afternoon which will be bring the heaviest rainfall to the Carolinas as well as points further north by later in the day on Saturday!
