INTERIOR SECTIONS OF PUERTO RICO. DUE TO ALREADY SATURATED
SOILS...ANY ADDITIONAL RAINFALL WILL LIKELY RESULT IN RAPID RISES IN
SMALL STREAMS AND CREEKS AS WELL AS INCREASE THE POTENTIAL FOR

Really,that tail from Alex is very long as it goes down to the Pacific and even dragging what is left of Darby. Stay safe and dry my friend.

[Macrocane]

I will cycloneye, thanks.

Orange Alert has just been declared in El Salvador the number of floods, mudslides, and other emergencies are increasing.

[Macrocane]

This is the rainfall between 7:00 am yesterday and 7:00 am today in El Salvador. The accumulated rain is not very high but I'm afraid that tomorrow's map will show much higher amounts.
