Subject: Corrected:Beach Hazards Statements issued by

†††††††† WFO Miami and WFO Key West to include information about

†††††††† Harmful Algal Blooms (HAB) when criteria are met,

†††††††† effective June 29, 2015

Florida WFOs (first link)

Effective Monday, June 29, 2015, at 2 pm Eastern Daylight Time

(EDT) or 1800 Coordinated Universal Time (UTC), harmful algal

bloom (HAB) forecast information provided by the National Ocean

Service (NOS) HAB Operational Forecast System (HAB-OFS), which

meets the criteria shown below, will be included in the Beach

Hazards Statements (BHS) being issued by WFO Miami and WFO Key

West during a HAB event when criteria described below are met.

An adjacent NWS office, WFO Tampa Bay Area, has been including

NOS HAB forecasts, when issuance criteria are met, in their BHS

since February 4, 2013. The addition of the two WFOs provides

more complete coverage of HABs affecting southwest Florida.

Starting on the above effective date, an NWS BHS for respiratory

irritation from HAB will be issued by WFOs Miami and Key West

for their areas of responsibility for a HAB of Karenia brevis

(commonly known as Florida Red Tide) if ALL of the following

criteria are met:

- HAB-OFS team has issued a HAB-OFS public conditions

††† report or update.

- Karenia brevis concentrations, which correlate to

††† Respiratory Irritation (>50,000 cells/L) have been confirmed

††† by in-situ cell counts in WFO Miami's and/or WFO Key West's

††† area of responsibility.

- HAB-OFS team forecasts high respiratory irritation is

††† possible in WFO Miami's or WFO Key West's area of

††† responsibility.

- If the level of forecasted respiratory irritation from HAB

††† decreases before the previously issued BHS for HAB

††† irritation expires, WFO Miami and/or WFO Key West will issue

††† a cancellation of the Beach Hazards Statement for HAB.

These are the same BHS criteria being used by WFO Tampa Bay Area

respiratory irritation from HAB.

A graphic showing the areas of responsibility for WFO Miami and

WFO Key West is online at (corrected link):


NWS issues the BHS under the NWS Coastal Hazard Message (CFW)

with a Valid Time Event Code (VTEC) of BH.S. The Beach Hazards

Statement is issued by many coastal WFOs for a variety of marine

hazards. A subset of the coastal WFOs also includes ecological

hazard information, such as HAB, in the BHS. Beach Hazards

Statements issued by the following WFOs are/will incorporate HAB

content when criteria are met:

WFO Tampa Bay Area: since February 2013

WFO Miami: as of June 29, 2015

WFO Key West: as of June 29, 2015

Routine HAB forecast products prepared by NOSí HAB-OFS are

issued via listserve and online once a week, at a minimum, or

twice a week during an active bloom.By including high

respiratory irritation from HABs in the NWS BHS, critical health

information is disseminated more broadly and in real-time to the

public.For more information about the HAB-OFS and the services

they provide, refer to:

(typo corrected in the following sentence)

WFOs Miami and Key West will coordinate with NOS' HAB analysts

concerning harmful algal blooms and potential health impacts on

coastal areas of southwest Florida as does WFO Tampa Bay Area.

The HAB analysts will provide information to WFOs Miami and Key

West on a bloom when high respiratory irritation associated with

a HAB is forecasted by the HAB-OFS. WFOs Miami and Key West will

relay that information in the Beach Hazards Statement for their

areas of responsibility. An HAB-OFS point of contact and other

local sources of red tide information will be included in all

Beach Hazards Statements which include HAB forecasts.


See the following links for an example of the BHS to be issued

by WFO Miami and WFO Key West for high respiratory irritation from HAB:


When in effect, Beach Hazard Statements issued by WFOs Miami and

Key West, as well as all of the additional WFOs issuing Beach

Hazards Statements, will be highlighted in turquoise on the NWS

Watch, Warning Advisory map:


Users interested in the BHS who are not already parsing the

Coastal Hazards Message (CFW) using the BH.S VTEC code (for

Beach Hazards Statement) may need to make the appropriate changes to

their software and/or systems to do so. Otherwise, no additional

changes are necessary.

The effective date of this change is sooner than specified by NWS

Instruction 10-1805. The reduction of the normal advance lead

time was approved because this change applies to only two WFOs

and will enable these offices to issue these products starting

July 1 when the need for this product increases. NWS has

coordinated with local partners. General background information

on VTEC can be found online at:
