IDC

After further review, FSB Scuba Director Joe Angelo has decided that the April IDC must be scratched.  The IDC dates overlap the two busiest program weeks of the Florida Sea Base spring program season and will pose too many logistical challenges to overcome.  I concur.  Additionally, only two people expressed any interest in the course and Joe felt that did not warrant the expense.  I apologize for this set back.  The IDC scheduled for September will likely make.

WEATHER ALERT

I received this email from Chip Kasper of the National Weather Service Office in Key West yesterday:
An Arctic blow will arrive Wednesday night in the Florida Keys.  However, both the strongest breezes and cooler and drier weather should be short-lived.
Air temperatures and humidity have been well above average in the Florida Keys since the third week in December, even while much of the country has been experiencing cold, ice, and snow.  Currently, a dome of cold, dry air of Arctic origin is spilling southward across the Canadian border into the Northern Plains.  A region of high pressure associated with this frigid air mass is expected to expand and intensify today through Wednesday, allowing the Arctic dome of cold air to plunge rapidly southeastward.  Its leading edge will sweep across the Gulf of Mexico and Florida Peninsula on Wednesday, reaching the Florida Keys around sunset (give or take a few hours).  Breezes, which have been blowing fresh overnight, actually will slacken later today, and remain fairly light through at least midday Wednesday.  The breeze will pick up from west to east Wednesday afternoon and evening, with due north winds picking up to a steady 25 knots most areas by daybreak Thursday.  The wind surge will peak during the Thursday morning hours, with a slow drop-off Thursday afternoon and night, and a lull Friday.  Measurable rain chances will be low, around 10 percent or less, with this front.  The “gustiness” factor will be elevated, though, as cold air arrives over warmer-than-average seas.  Frequent gusts around 30 knots are a distinct possibility late Wednesday night through midday Thursday.
We anticipate Small Craft Advisories going up for most zones by early Wednesday evening.
I have attached a couple of graphics showing predicted “significant wave height” valid at 7:00 a.m. and 1:00 p.m. EST on Thursday.  These graphics are produced by our experimental nearshore wave prediction system.  This system incorporates a forecaster-driven local nearshore wave model that resolves the complex water depths around the Florida Keys and accounts for ocean current-wave interactions.  Your feedback on this information is always welcome!
