is a low chance of isolated flash floods. Elsewhere, plan for
water ponding on roads and in poorly drained areas.

individuals extremely sensitive to heat, especially when outdoors
without effective cooling and/or adequate hydration. These
conditions are most likely across western PR.

The flood and lightning threat will remain through Saturday due
to the presence of moisture and an approaching trough. Marine and
