Re: Odd storm activity: double Invests!

We got 0.74" of rain since last evening, and some good breezy gusts this morning. Why? As Sparks notes, there are two separate low pressure spots passing our vicinity offshore (both are in the red hatched area on his NHC graphic: Tropical Depression Ileana far to the north is not affecting us anymore.) Here's the latest model predictions of the paths of the two lows (Invest 98E & 99E):
As you can see, they won't come any closer to us. The NHC says they will merge together and have a 90% chance of developing into a tropical depression or storm or hurricane in the next 48 hrs, as it continues off to the NW.
For today, we are still on the edge of this big developing storm, so we can expect some more rain. It might be a little windy also: the NHC E Pac Tropical Wx Discussion (http://www.nhc.noaa.gov/text/refresh/MIATWDEP+shtml/) mentions 20-30 knot winds from the east in our vicinity: "CURRENTLY THE PRESSURE GRADIENT BETWEEN STRONG HIGH PRESSURE BRIDGING SW ACROSS CENTRAL AMERICA AND LOW PRESSURE WITHIN THE BROAD MONSOON TROUGH HAS ENHANCED EASTERLY WINDS TO 20 TO 30 KT WITHIN 120 NM EITHER SIDE OF A LINE FROM 18N105W TO 13N97W." That line runs just offshore from our area down past the Oaxaca coastline, and we're well within the 120 nautical mile distance they mention.
So, another rainy weekend. This is the 5th weekend in a row with more than 1/2" of rain, including the 12.5" weekend in mid-August. Enjoy!
