The combination of a slow-moving frontal system and low pressure has resulted in as much as 8+ inches of rain in some spots and much the I-95 corridor from DC-to-Boston has been impacted. At mid-day, the heaviest of the rain is falling along coastal sections from New Jersey to southern New England, but flooding issues remain at inland locations. Residual showers are likely from later today into Wednesday and then nice weather is in store for Thursday, Friday and Saturday.
On the tropical scene, “Earl” is a strong tropical storm over the western Atlantic and moving slowly to the north. It will likely intensify into a hurricane over the next 24 hours or so - perhaps even a “major” - as it gradually turns to the northeast and likely avoiding any direct impact on the east coast. Meanwhile, the eastern Pacific features Hurricane “Kay” which could very well throw some moisture into southern California by the end of the week.
