An asymmetrical halo coronal mass ejection (CME) is associated with the X1.7 solar flare earlier this morning around Earth facing AR 4274. A passage past Earth will be likely within 48-72 hours. I would also expect a geomagnetic storm watch to be posted once this event is analyzed by NOAA/SWPC. A further update will be provided once this is available. See comments for a quick video.

Prayers for Jamaica. This hurricane has the potential to be catastrophic.

Jamaica is bracing for potentially its strongest storm to ever impact the island, as the slow-moving, major hurricane continues to close in.

As this line of storms approaches, in addition to strong winds and possible tornadoes, flash flooding is a major concern. We could expect to see 1”-2” of rain fall per hour, with an isolated possibility of up to 3.5” of rain per hour. The ground is hard and dry and will not be able to absorb that much water that quickly. So if you live in an area prone to flash floods, please take appropriate precautions.

While these cells are not currently severe, they are moving very slowly and dumping up to 2.5” of rain per hour.

If you get caught under one of these cells, be prepared for possible flash floods and never drive through water over the road.
