Previous Forecast

The center has been relocated to the southeast based on visible satellite imagery.

Visible satellite imagery has revealed a low-level center south of the thunderstorms associated with Tropical Storm Joyce. This has resulted in a re-location of the center a little south and east of where it was expected to be this afternoon. There are no changes to the forecast reasoning. Joyce is expected to track northwestward for another 4 days, followed by a turn to the north-northeast. Such a track would keep Joyce east of Bermuda. Forecasters do not expect any impact on the islands of the eastern Caribbean and probably little or no impact across the Canadian Maritimes.
