A Rainy Night

A rainy evening continues through the night. For most of northeast Broward the rain held off until about 5PM and it has rained almost ever since. As of 11PM Pompano has reported 2.23 inches of rain today.

As far as the low south of the central Bahamas, the NHC is planning on sending out a reconnaissance aircraft tomorrow to investigate the system. Below you will find the latest models on the system. Please keep in mind if the system were to develop, which there is less than a 30% chance of the occurring, intensity models do keep it well below hurricane strength.

I will post more tomorrow.

From the NHC

Here is the statement from the NHC from this afternoon. I will have more information later including model runs.

SATELLITE IMAGERY AND SURFACE OBSERVATIONS INDICATE THAT AN AREA OF
DISTURBED WEATHER HAS FORMED OVER EASTERN CUBA...THE SOUTHEASTERN
BAHAMAS...AND THE ADJACENT WATERS. SLOW DEVELOPMENT OF THIS SYSTEM
IS POSSIBLE DURING THE NEXT DAY OR TWO AS IT MOVES GENERALLY
NORTHWARD AT 10 TO 15 MPH. AN AIR FORCE RESERVE HURRICANE HUNTER
AIRCRAFT WILL INVESTIGATE THE SYSTEM ON TUESDAY...IF NECESSARY.
THERE IS A LOW CHANCE...LESS THAN 30 PERCENT...OF THIS SYSTEM
BECOMING A TROPICAL CYCLONE DURING THE NEXT 48 HOURS.

Early Season System?

Very quick post for now and I will expand on it tomorrow. Just looked at some of the models and a couple of them are indicating a closed low developing in the Gulf of Mexico sometime between late Monday into Wednesday. Way too early to say but we do have a cold front that should stall over central Florida late tomorrow and tropical moisture over the Caribbean that will be drawn up over our area during the next few days (remember rainy season is here). Sea surface temperatures are in the upper 70s to low 80s in the area so there are several reasons to watch this area.

More updates tomorrow, good night.

Funnel Clouds Off Boca this Morning



Thanks to Patrick Garmon for sending in these pictures from this morning. These funnel clouds/waterspouts were taken from the Yamato Road/Glades Road areas from Boca Raton looking east. Boca Raton air tower also observed these funnel clouds at 8:18am according a Special Marine Warning issued from the NWS in Miami.

The possiblity of waterspouts were noted in this morning's Harazrdous Weather Outlook issued at 3:44am this morning.

Speaking of funnels, the Vortex2 mission is now in day four. This has been covered widely on The Weather Channel and CNN. Today has been the first day they have been able to encounter severe weather and The Weather Channel has been giving them quite a bit of time. If you have the oppurtunity please tune in. It is very interesting to see how much equipment is being deployed to investigate tornadic developement.

Last but not least for tonight, we have less than 20 days before hurricane season begins. Of course that is when this blog becomes more active. This is the time that all of us should begin our preperations.
