Signs of good things to come...water temps abnormally warm for this time of year...I was out in boardshorts and rashguard yesterday for 3 hrs and wasn't cold at all...can't remember the last time the water was this warm, usually can't go without a suit before 4th of July....and this.... Invest #92L Lat: 7N, Lon:35.5W ...granted it may fizzle out to nothing, but at least there's activity! So psyched!!!! just hope that damn oil stays away!
Here is the Atlantic Tropical Outlook regarding the invest. CLOUDINESS...SHOWERS...AND THUNDERSTORMS ASSOCIATED WITH A BROAD AREA OF LOW PRESSURE LOCATED ABOUT 975 MILES SOUTHWEST OF THE SOUTHERNMOST CAPE VERDE ISLANDS HAVE BECOME BETTER ORGANIZED TODAY. ENVIRONMENTAL CONDITIONS APPEAR CONDUCIVE FOR ADDITIONAL SLOW DEVELOPMENT OF THIS SYSTEM OVER THE NEXT COUPLE OF DAYS AS IT MOVES WEST-NORTHWESTWARD OR NORTHWESTWARD AT 10 TO 15 MPH. THERE IS A MEDIUM CHANCE...50 PERCENT...OF THIS SYSTEM BECOMING A TROPICAL CYCLONE DURING THE NEXT 48 HOURS. If you look on the Atlantic Satellite loop, there is a fair amount of convection, although decreasing a bit this evening. It is extremely rare for a storm to develop in this part of the Atlantic this time of year, but conditions appear to be favorable.
Hey Swellinfo, On your storm tracking table for the tropical invest, the titles for your units of pressure read “mb (in)”. They don’t match with their values. Another note, how low does a low pressure system get? i.e. How many millibars (or whatever units) below atmospheric pressure does certain storms get? I wanted to start quantifying pressures of these low pressure systems. Thanks!
The pressure can drop extremely low, but tropical storms and hurricanes are not defined by the pressure, but rather the wind speeds. Changes in pressure and wind speed are generally directly correlated, but the two variables are not always consistent when comparing different storms. If you do see the pressure drop, however, this is an indication that the storm is strengthening. I've seen pressure drop in the upper 800 mbs before with major hurricanes. Here is a reference for you: http://www.eoearth.org/article/Tropical_weather_and_hurricanes This reference states, the low recorded pressure was 870 mb (during a typhoon), where most hurricanes have pressure around 950mb. The average sea level atmospheric pressure is 1 atm (atmosphere) or 101.3 kPa(kilopascals) or 1013.2 mb. If I can remember, on your sunny days, where high pressure takes over, the pressure can get around 1030mb or so. When the pressure drops below 1000mb then you generally have something significant brewing.
The pressure can vary from the upper 800s all the way to a thousand millibars in tropical storms and hurricanes depending on their strength.
http://www.nhc.noaa.gov/ i go on that all the time to see about the hurricanes. It def puts it up before weather.com talks about it. Hi ocsponger005
i am hoping for some good swell, but at the same time i hope the season isn't too devastating, and i'm kinda shakin over it. my neighborhood took a good beating from hurricane ernesto in 2006. remember ernesto? ya know that little peashooter category 1 hurricane labor day weekend of 06? i wasn't living there yet, but a few trees came down, and a couple of roofs down the block had some damage. hurricane isabel in 03 was like a category 5, and didn't do nearly the damage the little ernesto did. hurricane hanna a couple of years back wasn't so bad either, but long island got hit pretty good i think. i'm kinda slow when it comes to tracking those storms. i did check out where it was developing though. where does it look like it's headed from down there if it turns into a cyclone?
