Weather Alert in Florida
Hydrologic Outlook issued July 12 at 3:49PM EDT by NWS Miami FL
AREAS AFFECTED: Broward, FL; Collier, FL; Glades, FL; Hendry, FL; Miami-Dade, FL; Monroe, FL; Palm Beach, FL
DESCRIPTION: ESFMFL Broad low/mid level cyclonic flow around the disturbance, combined with the very high moisture values, will result in periods of rainfall at most times of the day, not just during peak diurnal cycles. The wind flow on Monday will be light due to a northerly in the upper levels and a light southerly flow at the surface. The 500 mb temp will also be around -4 to -5C which is warm for this time of year. This means that there could be nearly stationary showers and thunderstorms on Monday over South Florida which will exceed 1 inch over most of the area, with high-end amounts in excess of 3 inches, in some areas perhaps quite a bit higher. WPC's Excessive Rainfall Outlook is currently showing a slight risk of flooding over South Florida for Monday. Tuesday and Wednesday's rainfall amounts could be similar, if not even higher in some areas, as the wind flow shifts to S/SE direction allowing for deep tropical moisture to work into the region keeping the very high moisture values in place. WPC's Excessive Rainfall Outlook has put South Florida in a Slight Risk Of Flooding for Tuesday and Marginal Risk of Flooding for Wednesday. At this time, it looks like rainfall amounts of 2 to 4 inches with locally higher amounts up to 6 inches are possible through Wednesday. There could even be higher amounts with the storms train or sit over the same area. If these trends continue in later forecast through the weekend, but a Flood Watch may be needed for South Florida for early next week.

Next Topic: Cirrus Clouds
Cirrostratus clouds are high, thin clouds that form above
20,000 feet and are made mostly of ice crystals. They sometimes look like giant
feathers, horse tails, or curls of hair in the sky.
These clouds are pushed by the jet stream and can move at high speeds reaching
100 mph.
What do they indicate?
They indicate that a precipitation is likely within 24 hours.

Condensation is the process which creates clouds, and therefore
it is a crucial process in the water cycle.
Condensation is the change of matter from a state of gas into a state of liquid,
and it happens because water molecules release heat into the atmosphere and
become organized into a more closely packed structure, what we might see as
water droplets.
Water is always present in the air around us as a vapor, but it's too small for
us to see. When water undergoes the process of condensation it becomes organized
into visible water droplets. You've probably seen condensation happen before on the
surface of a cold drink!
