looks like epac is about to get a going! TROPICAL WEATHER DISCUSSION NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL 2205 UTC FRI MAY 12 2006 A 1008 MB SURFACE LOW MOVING W ABOUT 10-15 KT IS ANALYZED NEAR 8N97W. SCATTERED STRONG CONVECTION IN ASSOCIATION WITH THE LOW IS NOTED FROM 5N-11N BETWEEN 97W-100W. |

TROPICAL WEATHER DISCUSSION NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL 1005 UTC SAT MAY 13 2006 NUMEROUS STRONG CONVECTION WITHIN 240 NM OF 8N94W ASSOCIATED WITH A LOW PRES CENTER NEAR 9N96W. A WEAK LOW PRES CENTER 1007 MB WAS NEAR 9N96W MOVING SLOWLY WWD. QUIKSCAT SHOWS WINDS TO 25 KT WITHIN 300 NM OF THE CENTER. THERE APPEARS TO BE AN INCREASE IN CONVECTION DURING THE PAST 24 HRS MAINLY E OF THE CENTER. THE ANTICYCLONIC OUTFLOW OVER THE SYSTEM HAS BECOME BETTER DURING THE NIGHT. http://manati.orbit.nesdis.noaa.gov/dataimages21/cur_hires/zooms/WMBds65.png |

I think the first tropical wave of the season deserves a new thread, don't you? http://www.ssd.noaa.gov/goes/east/catl/loop-vis.html |

Hi guys, Is it normal for a wave this time of year? Thanks, Christine |

Quote:Thanks. It seems WWD means Wind Wave Direction, or the direction in which (surface?) wind and waves are moving, as reported for example from a buoy like that displayed at http://www.ndbc.noaa.gov/station_page.php?station=42035. It seems WWD is recorded as being from 0 - 360 degrees and is reported as a compass point, e.g., SSW. By comparing the movement of clouds visible in that area with the little red flags shown when the "HDW-low" box is clicked at http://www.ssd.noaa.gov/goes/east/watl/loop-vis.html, the buoys (and/or vessels I suppose) nearest that latitude and longitude seem to be indicating (??) that the low pressure is rotating in a counter-clockwise pattern. Beyond that I don't see much else to help me understand what "MOVING SLOWLY WWD" might be saying. Again, thanks. |

WWD means westward.... |

Quote:Golly, there's even more hits for WWD, weather and westward! And yes forecasters definately use it that way. Clearly I should have paged further forward through the search results. But at least I found out where the little red flags come from (or at least perhaps one of them - most seem to be moving and some seem to be missing). Thanks! |

Thanks for the wake up call! So... more or less on June 1, wind currents change to allow tropical waves to move further WWD. Because this one, or at least the convection associated with it, seems about to start moving northeast. http://www.ssd.noaa.gov/goes/east/catl/loop-avn.html In addition to water tempaeratures is that why the Atlantic hurricane season officially begins in June? |

The eastpac TWD have been kind of droll this weekend, with the discussion first separating the area to the east and west of a given longitude, then to the north and south of a given latitude, now this morning's separated into upper level and surface features. * * * * * * * We have 90E. This morning's TWD was right on the money. I started a new thread. |
