After a really wild weather day yesterday, today is quite tranquil.
Baseball-sized hail fell across south Texas in the late afternoon
destroying roofs and automobiles. So far I have not seen any reports of
bird mortality but a similar storm some years back killed a couple of
thousand Reddish Egrets at the Green Island rookery and destroyed virtually
all the nests.
Today upper winds are S 15 at Brownsville and N 12 at Lake Charles. There
should be a pretty good display of passerine and other migrants on the
upper Texas and Louisiana coasts but again I have seen no reports.
Brownsville is again showing a "halo" figure indicating that birds are
overflying the NEXRAD station and continuing. They are headed straight N up
the coast. No other stations were showing approaching trans-Gulf migrants
at noon.
The forecast is for a couple of days of rainy weather tomorrow and
Wednesday so migrant birding should be rewarding for the first half of the
week.
